Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0043] The present application provides a constant-temperature water bath box 100 for film development, which is convenient for users to control the temperature of the chemical liquid for film development, and in particular can reduce the temperature of the chemical liquid contained in the chemical liquid tank 200. The specific scheme is illustrated by the following embodiments.

[0044] The developer solution in the developer solution tank 200 can be a developing solution, a fixing solution, a stop developing solution, etc.

[0045] Referring to Figure 1 The constant temperature water bath box 100 comprises a box body 10, and the box body 10 is provided with a containing groove 11 for containing a temperature guide medium. The developer solution tank 200 is at least partially contained in the containing groove 11 and is immersed in the temperature guide medium.

[0046] The temperature guide medium can be water. In other embodiments, the temperature guide medium can also be other solutions with heat transfer or cold transfer performance.

[0047] Referring to Figure 2 In some embodiments, the constant temperature water bath box 100 comprises a mounting disc 20. The mounting disc 20 is provided corresponding to the slot of the containing groove 11. The mounting disc 20 is provided with a plurality of mounting positions 21. Each mounting position 21 is used for fixing the developer solution tank 200.

[0048] Specifically in the embodiment, the mounting position 21 is a mounting hole. The developer solution tank 200 can be contained in the bottom of the box body 10 by penetrating the mounting hole. The diameter of the mounting hole is related to the diameter of the developer solution tank 200. In addition, the diameters of the plurality of mounting holes can be set to be the same size; or the diameters of the mounting holes can also be set to be different sizes, so that the constant temperature water bath box 100 of the application can be suitable for developer solution tanks 200 of various sizes, and the versatility of the constant temperature water bath box 100 is improved.

[0049] In other embodiments, the way of fixing the developer solution tank 200 can also be set to other forms. For example, the constant temperature water bath box 100 comprises a plurality of fixing lines, the plurality of fixing lines are arranged in the containing groove 11 of the box body 10, and are arranged in a grid structure in a longitudinal and transverse manner. Each developer solution tank 200 can be correspondingly contained in a grid. Such a structure can be arranged in multiple layers along the height direction of the box body 10, thereby facilitating to enhance the stability of the developer solution tank 200.

[0050] It should be noted that the mounting position 21 can be used not only for fixing the developer solution tank 200, but also for fixing other containers containing developer solution, such as a measuring cup, etc.

[0051] Referring to Figure 3 and Figure 4 In some embodiments, opposite sides of the box body 10 are provided with carrying portions 13, so as to facilitate a user to hold the carrying portions 13 with both hands respectively and move the constant temperature water bath box 100.

[0052] Referring to Figure 5 The constant temperature water bath box 100 comprises a control assembly 30 and a refrigeration module 40.

[0053] The control assembly 30 comprises a shell 31 and a main control board 32. The shell 31 is at least partially accommodated in the accommodating groove 11. The main control board 32 is arranged inside the shell 31 to facilitate protection of the main control board 32. It should be noted that the shell 31 can be arranged at any position in the accommodating groove 11 and can be arranged according to actual needs. In this embodiment, the shell 31 is arranged at a corner of the box body 10.

[0054] The refrigeration module 40 is electrically connected to the main control board 32 and is controlled to be turned on and turned off by the control assembly 30. The refrigeration module 40 can generate cold energy under the control of the control assembly 30, and the cold energy is transferred to the temperature-conducting medium to reduce the temperature of the temperature-conducting medium. The chemical solution tank 200 immersed in the temperature-conducting medium is affected by the temperature of the temperature-conducting medium, and the temperature of the chemical solution contained therein also decreases as the temperature of the temperature-conducting medium decreases. In other words, the constant-temperature water bath box 100 of the present application reduces the temperature of the developing solution, fixing solution and other chemical solutions contained in the chemical solution tank 200 in a manner similar to water bath cooling to meet the temperature requirements of users when washing films, especially black and white films.

[0055] Further, the refrigeration module 40 is arranged on the peripheral wall corresponding to the accommodating groove 11. The refrigeration module 40 can generate cold energy, and the cold energy is conducted to the temperature-conducting medium through the peripheral wall to reduce the temperature of the temperature-conducting medium.

[0056] The peripheral wall can be the side wall and the bottom wall surrounding the box body 10, or the side wall and the bottom wall surrounding the shell 31 of the control assembly 30. In other words, the refrigeration module 40 can be arranged on the side of the bottom wall of the box body 10 away from the accommodating groove 11; or the refrigeration module 40 can be arranged on the side of the side wall of the box body 10 away from the accommodating groove 11; or the refrigeration module 40 can be arranged on the side of the side wall of the shell 31 away from the accommodating groove 11; or the refrigeration module 40 can be arranged on the side of the bottom wall of the shell 31 away from the accommodating groove 11.

[0057] It should be noted that when the refrigeration module 40 is arranged on the bottom wall of the shell 31, there is a certain gap between the bottom wall of the shell 31 and the bottom wall of the box body 10, and the temperature-conducting medium is filled in the gap, so that the side surface of the bottom wall of the shell 31 close to the bottom wall of the box body 10 can be immersed in the temperature-conducting medium, thereby ensuring that the cold energy generated by the refrigeration module 40 can be conducted to the temperature-conducting medium through the bottom wall of the shell 31.

[0058] In this embodiment, the refrigeration module 40 is arranged inside the shell 31, and the refrigeration module 40 is arranged on the side wall of the shell 31. The side wall is preferably the side wall close to the mounting position 21 of the mounting disc 20.

[0059] For example, the cooling module 40 is a semiconductor cooling device, which includes a first surface and a second surface disposed opposite to each other, with the first surface in contact with the side wall of the housing 31. When the semiconductor cooling device is energized, the first surface generates cooling energy, and the second surface generates heat energy. Therefore, the cooling energy generated by the cooling module 40 is directly conducted to the side wall of the housing 31, and then to the heat-conducting medium.

[0060] It should be noted that the area of ​​the sidewall in contact with the semiconductor cooling component can be made of a material with good conductivity, such as silver, copper, or aluminum.

[0061] Continue reading Figure 5 In some embodiments, the constant temperature water bath 100 includes at least one cold-conducting plate 50, which is used to conduct the cooling energy generated by the refrigeration module 40. Specifically, the cold-conducting plate 50 is disposed corresponding to the refrigeration module 40, and the cold-conducting plate 50 can be immersed in the heat-conducting medium. In this embodiment, the cold-conducting plate 50 protrudes from the side wall of the housing 31, so that the cooling energy generated by the refrigeration module 40 can be conducted to the cold-conducting plate 50 through the side wall. It can be understood that the arrangement of the cold-conducting plate 50 increases the cooling area, which is beneficial to accelerating the cooling of the heat-conducting medium.

[0062] It should be noted that the appendix Figure 5 The cold-conducting plate 50 shown is vertically disposed on the side wall of the housing 31, extending outward toward the outside of the housing 31, and is arranged laterally. In other embodiments, the cold-conducting plate 50 can also be arranged vertically, obliquely, etc. When multiple cold-conducting plates 50 are provided, the multiple cold-conducting plates 50 can be arranged in an array or staggered, etc. The specific configuration can be set according to the implementation needs, and is not limited here.

[0063] In some embodiments, the constant temperature water bath 100 includes a heat dissipation module 60, which is disposed on the second surface of the thermoelectric cooler. Therefore, when the thermoelectric cooler is powered on, the heat generated on the second surface can be transferred to the environment through the heat dissipation module 60. The heat dissipation module 60 may include a copper plate and heat dissipation fins; or the heat dissipation module 60 may include copper pipes and heat dissipation fins, etc., which can be specifically configured according to actual needs.

[0064] In some embodiments, the constant temperature water bath 100 includes a heating module 70, which is electrically connected to the main control board 32. The heating module 70 generates heat when powered on. The heating module 70 is at least partially immersed in a heat-conducting medium, so that the heat generated by the heating module 70 can be conducted to the heat-conducting medium to raise its temperature.

[0065] It can be understood that the arrangement of the heating module 70 enables the constant-temperature water bath tank 100 of the present application to also have a heating function, which can increase the temperature of the temperature guide medium, and in turn increase the temperature of the developer in the developer tank 200, so as to meet the temperature requirement of the developer required for film development, especially for color film development.

[0066] In practice, the heating module 70 is arranged on the housing 31 of the control assembly 30. Specifically, the heating module 70 comprises a heating disc 71, a circuit board 72, and a heating disc electrode 73, the heating disc 71 being electrically connected to the circuit board 72 through the heating disc electrode 73. The circuit board 72 and the heating disc electrode 73 are arranged inside the housing 31, so as to prolong the service life. The circuit board 72 is also electrically connected to the main control board 32. The heating disc 71 is arranged on the outer wall of the housing 31, so that when the heating module 70 is powered on, the heat generated by the heating disc 71 can be transferred to the temperature guide medium, which is conducive to accelerating the temperature rise of the temperature guide medium.

[0067] It should be noted that the heating disc 71 can be arranged on the side wall of the housing 31, or the heating disc 71 can also be arranged on the side surface of the bottom wall of the housing 31 close to the bottom wall of the tank body 10, at this time, there is a certain gap between the bottom wall of the housing 31 and the bottom wall of the tank body 10, and the temperature guide medium is filled in the gap, so that the side surface of the bottom wall of the housing 31 close to the bottom wall of the tank body 10 can be immersed in the temperature guide medium, thereby ensuring that the heat generated by the heating disc 71 can be directly transferred to the temperature guide medium. The present embodiment is described by way of example with the heating disc 71 arranged on the bottom wall of the housing 31.

[0068] It should be noted that in some other embodiments of the present application, the arrangement of the heating module 70 can be cancelled, and other ways of heating can be adopted. For example, the main control board 32 comprises a current reversing control module, which is used to change the direction of the current passing through the semiconductor refrigeration piece, so that the first surface generates heat and the second surface generates cold, at this time, the heat generated by the first surface is in contact with the side wall of the housing 31 to transfer heat to the housing 31, and then to the temperature guide medium.

[0069] See Figure 5 In some embodiments, the accommodating groove 11 of the tank body 10 is provided with a partition plate 12, which divides the accommodating groove 11 into a temperature control cavity 111 and a constant-temperature cavity 112. The temperature control cavity 111 and the constant-temperature cavity 112 both contain the temperature guide medium. The control assembly 30 can be arranged in the temperature control cavity 111. The constant-temperature cavity 112 is used to contain the developer tank 200.

[0070] The end surface of the partition plate 12 away from the bottom wall of the tank body 10 abuts against the side surface of the mounting disc 20 close to the bottom wall of the tank body 10, that is, the arrangement of the partition plate 12 forms a support for the mounting disc 20, which is conducive to ensuring the stability of the mounting disc 20.

[0071] Further, the housing 31 of the control assembly 30 can extend outwardly at a side near the top of the mounting disc 20, or can be recessed inwardly at a side near the bottom of the mounting disc 20, so that the housing 31 forms a stepped structure 311 at a side near the mounting disc 20. The stepped structure 311 abuts against a side surface of the mounting disc 20 away from the partition 12. The stepped structure 311 cooperates with the mounting disc 20 to ensure the stability of the housing 31 in the accommodation groove 11.

[0072] Referring to Figure 5 and Figure 6 In some embodiments, the housing 31 of the control assembly 30 is provided with a recess 312 at the top. The control assembly 30 includes a display screen electrically connected to the main control board 32, which is arranged in the recess 312 and has a display surface facing outwardly of the housing 31. The display screen can interact with a user, so that the user can control the opening and closing of the refrigeration module 40 and the heating module 70 by touching the display screen. Alternatively, in other embodiments, the display screen can only be used for the user to view relevant information, and buttons or knobs for controlling the refrigeration module 40 and the heating module 70 can be additionally provided.

[0073] In some embodiments, the constant-temperature water bath 100 includes a temperature measuring instrument 80 for measuring the temperature of the temperature-conducting medium in the accommodation groove 11. The temperature measuring instrument 80 is electrically connected to the main control board 32 to transmit a temperature signal of the temperature-conducting medium to the main control board 32, so that the main control board 32 controls the refrigeration module 40 according to the temperature signal. In addition, the temperature data detected by the temperature measuring instrument 80 can also be displayed on the display screen in real time, so as to facilitate the user to accurately control the temperature of the temperature-conducting medium.

[0074] For example, an end of the temperature measuring instrument 80 is arranged in the housing 31 and accommodated in the accommodation groove 11. Specifically, the housing 31 is provided with a through hole in a bottom wall, and the temperature measuring instrument 80 is arranged in the through hole and accommodated in the bottom of the accommodation groove 11. The control assembly 30 includes a sealing ring 33 arranged around the temperature measuring instrument 80. The sealing ring 33 is used to seal the gap between the through hole and the temperature measuring instrument 80, so as to prevent the temperature-conducting medium from entering the interior of the housing 31 and damaging the refrigeration module 40, the heating module 70, etc.

[0075] In some embodiments, the control assembly 30 includes a baffle 34 arranged at the bottom of the housing 31 and surrounding the outer periphery of the portion of the temperature measuring instrument 80 outside the housing 31. The baffle 34 is arranged to protect the temperature measuring instrument 80 from being damaged when the control assembly 30 is mounted or dismounted on the cabinet 10. The baffle 34 is provided with a liquid flow port 341, so as to ensure that the temperature-conducting medium can smoothly fill between the housing 31 and the cabinet 10, ensure the normal operation of the temperature measuring instrument 80, and avoid affecting the temperature measurement of the temperature measuring instrument 80 on the temperature-conducting medium.

[0076] The baffle 34 can be formed by extending the peripheral wall of the shell 31 toward the bottom wall of the tank 10 in the height direction of the tank 10, that is, the baffle 34 can be integrally arranged with the peripheral wall of the shell 31. In addition, it can be understood that the length of the baffle 34 is not less than the length of the temperature measuring instrument 80 exceeding the shell 31. In an implementation, the length of the baffle 34 is the same as the spacing between the bottom wall of the shell 31 and the bottom wall of the tank 10, that is, the baffle 34 is in contact with the bottom wall of the tank 10, at this time, the bottom wall of the tank 10 supports the shell 31, which further helps the stability of the shell 31 in the accommodating groove 11.

[0077] Referring to Figure 5 and Figure 6 In some embodiments of the present application, the constant-temperature water bath tank 100 comprises a circulating assembly 90. The circulating assembly 90 is used to promote the flow of the temperature-conducting medium to promote the uniform and rapid spreading of heat or cold, and to ensure the temperature uniformity of the temperature-conducting medium at all places in the accommodating groove 11, so as to ensure the temperature uniformity of the medicinal liquid in the medicinal liquid tank 200.

[0078] In some embodiments, the circulating assembly 90 is electrically connected to the main control board 32, and the circulating assembly 90 is provided with at least one set. The circulating assembly 90 comprises a driving pump 91, an inlet pipe 92 and an outlet pipe 93. The driving pump 91 is electrically connected to the main control board 32. One end of the inlet pipe 92 and the outlet pipe 93 is connected to the driving pump 91, and the other end of the inlet pipe 92 and the outlet pipe 93 is accommodated in the accommodating groove 11 and can be immersed in the temperature-conducting medium. The driving pump 91 is powered to make the temperature-conducting medium flow into the driving pump 91 through the inlet pipe 92 and flow out of the outlet pipe 93, so that the temperature-conducting medium circulates in the accommodating groove.

[0079] Specifically in the present embodiment, the circulating assembly 90 is provided with one set. The driving pump 91 in the circulating assembly 90 is arranged on the shell 31. The driving pump 91 is electrically connected to the main control board 32. The partition plate 12 separating the accommodating groove 11 into the temperature control cavity 111 and the constant-temperature cavity 112 is provided with a communication hole 121, so that the temperature control cavity 111 and the constant-temperature cavity 112 are communicated. Exemplarily, the inlet pipe 92 is arranged in the temperature control cavity 111, and the outlet pipe 93 is arranged in the constant-temperature cavity 112 by penetrating the partition plate 12. The driving pump 91 is started to make the temperature-conducting medium in the temperature control cavity 111 flow from the inlet pipe 92 to the outlet pipe 93, so as to be mixed with the temperature-conducting medium in the constant-temperature cavity 112. The communication hole 121 is arranged to make the temperature control cavity 111 and the constant-temperature cavity 112 communicate, so that the temperature-conducting medium in the constant-temperature cavity 112 automatically flows into the temperature control cavity 111 through the communication hole 121.

[0080] It can be understood that the heat generated by the heating module 70 and / or the cold generated by the refrigeration module 40 is first conducted to the temperature-conducting medium in the temperature-control cavity 111. Therefore, the arrangement of the above-mentioned circulating assembly 90 enables the temperature-conducting medium to flow between the temperature-control cavity 111 and the constant-temperature cavity 112, thereby achieving the temperature uniformity of the temperature-conducting medium.

[0081] Referring to Figure 7 , Figure 7 is another embodiment of the constant-temperature water bath 100 of the present application, which is mainly different from the embodiment shown in Figure 5 in that the constant-temperature water bath 100 cancels the arrangement of the heating module 70, and adopts another circulating assembly 90 to facilitate the flow of the temperature-conducting medium. Specifically, the circulating assembly 90 comprises an impeller 95 arranged in the accommodating groove 11 and an electric motor 94 electrically connected to the main control board 32. The electric motor 94 is energized to drive the impeller 95 to rotate, agitate the temperature-conducting medium contained in the accommodating groove 11, and realize the flow of the temperature-conducting medium in the accommodating groove 11 of the box body 10.

[0082] Practically, the electric motor 94 is arranged inside the shell 31, and the impeller 95 is arranged on the bottom wall of the shell 31 and located outside the shell 31 to facilitate being immersed in the temperature-conducting medium.

[0083] Referring to Figure 8 , Figure 8 is another embodiment of the constant-temperature water bath 100 of the present application, which is mainly different from the embodiment shown in Figure 5 in that the partition plate 12 cancels the arrangement of the communication hole 121 communicating the temperature-control cavity 111 and the constant-temperature cavity 112. The circulating assembly 90 is provided with two, i.e., two driving pumps 91, two liquid inlet pipes 92 and two liquid outlet pipes 93.

[0084] For the convenience of description, the two driving pumps 91 are defined as a first driving pump 911 and a second driving pump 912, the two liquid inlet pipes 92 are defined as a first liquid inlet pipe 921 and a second liquid inlet pipe 922, and the two liquid outlet pipes 93 are defined as a first liquid outlet pipe 931 and a second liquid outlet pipe 932.

[0085] The first driving pump 911 and the second driving pump 912 can be arranged on the shell 31 of the control assembly 30. One end of the first liquid inlet pipe 921 is connected to the first driving pump 911, and the other end is arranged in the temperature control cavity 111. One end of the first liquid outlet pipe 931 is connected to the first driving pump 911, and the other end is arranged in the constant temperature cavity 112 through the partition plate 12. One end of the second liquid inlet pipe 922 is connected to the second driving pump 912, and the other end is arranged in the constant temperature cavity 112 through the partition plate 12. One end of the second liquid outlet pipe 932 is connected to the second driving pump 912, and the other end is arranged in the temperature control cavity 111. The first driving pump 911 and the second driving pump 912 are started at the same time, so that the temperature guide medium can flow circularly between the temperature control cavity 111 and the constant temperature cavity 112.

[0086] In an embodiment, two openings can be arranged on the partition plate 12, and the first liquid outlet pipe 931 and the second liquid inlet pipe 922 are arranged in the constant temperature cavity 112 through the corresponding openings. Further, a sealing member such as a sealing ring 33 can be arranged between the openings and the pipes.

[0087] Referring to Figure 9 , Figure 9 is another embodiment of the constant temperature water bath box 100 of the present application, which is mainly different from the embodiment shown in Figure 8 in that the control assembly 30 further comprises a shell 35, at least part of the shell 35 is arranged in the temperature control cavity 111 of the accommodating groove. The shell 35 is wrapped outside the shell 31. The space between the shell 35 and the shell 31 forms a partition cavity, and the temperature guide medium is arranged in the partition cavity. The circulating assembly 90 comprises a water inlet pipe and a water outlet pipe, which are respectively connected to the partition cavity and the accommodating groove 11, so that the temperature guide medium can flow between the partition cavity and the accommodating groove 11. The control assembly 30 is usually provided with a charging interface or a plug-in interface, so that the arrangement of the shell 35 can effectively prevent the outside of the control assembly 30 from touching the temperature guide medium when the control assembly 30 is installed on the box body 10, thereby facilitating the protection of the charging interface or the plug-in interface on the control assembly 30.

[0088] It should be noted that the water inlet pipe and the water outlet pipe here are the first liquid outlet pipe 931 and the second liquid inlet pipe 922 shown in Figure 8 In this embodiment, two mounting grooves can be arranged on the top of the partition plate 12, and the first liquid outlet pipe 931 and the second liquid inlet pipe 922 are arranged in the two mounting grooves.

[0089] In some embodiments, the control assembly 30 can further be provided with a handle on the shell 35, so as to facilitate the user to hold and place the control assembly 30, and facilitate the assembly and disassembly between the control assembly 30 and the box body 10.

[0090] Please refer to Figure 10The application also provides a film developing machine, which comprises the roll developing control mechanism 300, the developing tank 400 and the constant-temperature water bath box 100. The developing tank 400 is arranged in the accommodating groove 11 of the constant-temperature water bath box 100 and can be at least partially immersed in the temperature-conducting medium in the accommodating groove 11.

[0091] It should be noted that the developing tank 400 is a container for placing films and chemicals to realize film development.

[0092] The roll developing control mechanism 300 is connected with the developing tank 400 and drives the developing tank 400 to rotate, so that the temperature of the chemicals in the developing tank 400 is synchronized while ensuring that the films are fully and uniformly contacted with the chemicals to fully and uniformly react, thereby effectively improving the film development effect.

[0093] In some embodiments, the roll developing control mechanism 300 is provided with a driving motor 94, and the rotating shaft of the driving motor 94 is connected with the developing tank 400 to drive the developing tank 400 to rotate. The developing tank 400 can be approximately in a cylindrical structure, and the central axis thereof can coincide with the axis of the rotating shaft.

[0094] The roll developing control mechanism 300 can control the developing tank 400 to rotate at a set rotating speed. For example, the roll developing control mechanism 300 is electrically connected with the main control board 32 of the control assembly 30, so that the user can control the rotating speed of the developing tank 400 by operating the control assembly 30.

[0095] In some embodiments, the mounting plate 20 is provided with an opening 22, and the user can operate the roll developing control mechanism 300 and the developing tank 400 in the accommodating groove 11 through the opening 22.

[0096] The constant-temperature water bath box 100 of the application can reduce the temperature of the developing liquid, fixing liquid and other chemicals in the chemical tank 200 by setting the box body 10, the control assembly 30 and the refrigeration module 40, thereby realizing the control of the temperature of the chemicals. Compared with manually controlling the temperature of the chemicals, the constant-temperature water bath box of the application is convenient and safe to operate. In addition, the constant-temperature water bath box 100 can further comprise a circulating assembly 90 and a temperature measuring instrument 80. The circulating assembly 90, the refrigeration module 40 and the temperature measuring instrument 80 can be integrally arranged on the housing 31 of the control assembly 30, so that the structure of the constant-temperature water bath box 100 is more compact, facilitating assembly and facilitating current flow. The constant-temperature water bath box 100 can be further provided with a heating module 70, so that the constant-temperature water bath box 100 of the application also has the function of heating. The user can control the start of the heating module 70 or the refrigeration module 40 according to the actual situation. Alternatively, the main control board 32 is provided with a temperature control unit, which can automatically start the heating module 70 or the refrigeration module 40 according to the temperature set by the user.
