[0039] Referring to Figures 1 to 3 An embodiment of the present application provides a washing tank 100 for developing and washing films, which comprises a developing inner tank 10, a film core 20, a constant-temperature outer tank 30 and a refrigeration module 40.

[0040] The developing inner tank 10 is internally provided with a space for accommodating the developing solution. The film core 20 is arranged in the interior of the developing inner tank 10, and is used for fixing the film. The constant-temperature outer tank 30 is arranged outside the developing inner tank 10, and a constant-temperature layer 101 is formed between the developing inner tank 10 and the constant-temperature outer tank 30, and the constant-temperature layer 101 is filled with a temperature-conducting medium.

[0041] The refrigeration module 40 is arranged in the constant-temperature layer 101, and the refrigeration module 40 can generate cold energy when powered on, and the cold energy generated by the refrigeration module 40 can be transmitted to the developing inner tank 10 through the temperature-conducting medium, so as to reduce the temperature of the developing solution in the developing inner tank 10.

[0042] In the present application, the refrigeration module 40 can directly act on the temperature-conducting medium in the constant-temperature layer 101 to transmit cold energy to the developing inner tank 10 to quickly reduce the temperature of the developing solution, thereby breaking through the limitation that the traditional developing solution needs to rely on the refrigerator for cooling. Moreover, the temperature-conducting medium in the constant-temperature layer 101 uniformly transmits cold energy through heat conduction, avoids local temperature deviation of the developing inner tank 10, ensures that the film is in contact with the solution with uniform temperature in the whole film width, reduces uneven development caused by temperature difference, and improves the consistency of the washing quality. In addition, the refrigeration module 40 arranged in the constant-temperature layer 101 can maintain the developing solution at a target low temperature, thereby solving the problem that the low-temperature state of the developing solution is difficult to control in the case of high ambient temperature, and effectively ensuring the quality of film washing.

[0043] In some embodiments of the present application, the constant-temperature outer tank 30 includes an outer tank body 31 and an outer cover body 32. One end of the outer tank body 31 is provided with an outer opening, and the outer wall of the outer tank body 31 corresponding to the outer opening is provided with an outer thread. The inner wall of the outer cover body 32 is provided with an inner thread, and the inner thread and the outer thread are screw-connected and adapted, so that the outer cover body 32 is detachably connected at the outer opening of the outer tank body 31.

[0044] The outer cover body 32 and the outer tank body 31 are detachably connected through threaded connection, so that the outer cover body 32 can be easily unscrewed, which is convenient for user operation. Moreover, the threaded connection mode of the two is also convenient for replacement and replenishment of the temperature-conducting medium in the constant-temperature layer 101.

[0045] In other examples, in addition to the threaded connection mode, the detachable connection of the outer cover body 32 and the outer tank body 31 can also be achieved through other structural forms, such as an elastic buckle can be arranged at the edge of the outer opening of the outer tank body 31, and a clamping groove is arranged at the corresponding position of the inner wall of the outer cover body 32, and the outer cover body 32 is detachably connected to the outer tank body 31 through the clamping of the elastic buckle and the clamping groove; or a hasp base can be arranged on the outer side of the outer tank body 31, and a hasp is arranged at the corresponding position of the outer cover body 32, and the outer cover body 32 and the outer tank body 31 are detachably connected through the buckling of the hasp and the hasp base.

[0046] In some examples, the outer tank body 31 is provided with a fitting groove 311 on the outer side of the outer opening, which is recessed towards the inside of the outer tank body 31. In this example, the outer tank body 31 further comprises a fitting cover 33, the outer wall of the outer tank body 31 is provided with a connecting column 312 corresponding to the fitting groove 311, and the fitting cover 33 is provided with a fitting hole 331 corresponding to the connecting column 312. A fitting member is arranged in the fitting hole 331 to be fixed in the connecting hole 313 of the connecting column 312, so that the fitting cover 33 is fixed on the outer wall of the outer tank body 31.

[0047] In some examples, the fitting member can be a screw, a pin, etc. The fitting cover 33 is fixed to the outer wall of the outer tank body 31, and a fitting space can be formed between the fitting cover 33 and the outer tank body 31 corresponding to the fitting groove 311. The fitting space can be used to assemble electrical elements to avoid contact between the electrical elements and the temperature guide medium in the constant-temperature interlayer 101.

[0048] In some examples, the constant-temperature outer tank 30 further comprises a sealing ring 34 arranged at the outer opening of the outer tank body 31, and the sealing ring 34 forms a seal between the outer tank body 31 and the outer cover body 32.

[0049] The sealing ring 34 can be made of silicone or rubber, which can fill the connection gap between the outer tank body 31 and the outer cover body 32 by extrusion deformation, prevent the temperature guide medium from leaking from the interface, avoid the failure of the constant-temperature function due to the loss of liquid, and affect the temperature control accuracy of the developing liquid.

[0050] Further, as shown in Figure 3 and Figure 4 In this application, the developing inner tank 10 is arranged inside the constant-temperature outer tank 30. The constant-temperature outer tank 30 and the developing inner tank 10 form a constant-temperature interlayer 101, which is filled with a temperature guide medium.

[0051] In some examples, the temperature guide medium can be water, which has a high temperature guide coefficient, a large specific heat capacity, and a low cost, and is environmentally friendly and non-toxic. The temperature guide medium can be an aqueous glycol solution, which has a low freezing point and is suitable for scenes requiring a low-temperature developing environment (such as 18℃-20℃ constant temperature for some black and white film development) or cold environments to avoid freezing of the interlayer. The temperature guide medium can be heat-conducting oil, which has a high boiling point, a low freezing point, good chemical stability, and no corrosiveness.

[0052] In other examples, the temperature guide medium can also be selected from other substances such as silicone oil, molten salt, and air according to the use requirements, which are not limited herein.

[0053] As shown in Figure 4 In some embodiments of the application, the developing inner tank 10 comprises an inner tank body 11 and an inner cover body 12. One end of the inner tank body 11 is provided with an inner opening, and the inner cover body 12 is connected at the inner opening of the inner tank body 11.

[0054] In some examples, the inner tank body 11 includes a barrel 111 and a bottom plate 112 connected to the barrel 111. The barrel 111 is open at both ends and hollow inside. One end of the barrel 111 is open to form an inner opening. The other end of the barrel 111 is open to form a bottom opening. The bottom plate 112 is connected to the bottom opening.

[0055] In this example, the bottom plate 112 of the inner tank body 11 is provided with a limiting groove 113. The limiting groove 113 is arranged protruding towards the outside of the inner tank body 11. The edges of the barrel 111 corresponding to the bottom opening all protrude outward beyond the circumferential side of the bottom plate 112. The part of the barrel 111 protruding beyond the bottom plate 112 at the end is arranged around the circumferential side of the limiting groove 113.

[0056] For the flushing tank 100 of this example, when the developing inner tank 10 is installed in the constant-temperature outer tank 30, the limiting groove 113 can cooperate with the inner wall of the constant-temperature outer tank 30 to achieve rapid positioning of the developing inner tank 10, avoid the developing inner tank 10 from shaking or deviating in the constant-temperature interlayer 101, ensure uniform distribution of the temperature-conducting medium in the constant-temperature interlayer 101, and improve the stability of temperature conduction.

[0057] In some examples, the inner cover body 12 can include a fastening cover 121, a connecting cover 122, and a fastening ring 123. The fastening cover 121 includes a cover main body 1211 and a clamping arm 1212 connected to the cover main body 1211. The cover main body 1211 is open at both ends and hollow inside. The two ends of the cover main body 1211 are respectively a first opening and a second opening.

[0058] The connecting cover 122 is connected to the first opening. The connecting cover 122 is clamped and fixed with the end of the cover main body 1211, so that the connecting cover 122 is detachably connected to the fastening cover 121.

[0059] The clamping arm 1212 is provided in plurality. The plurality of clamping arms 1212 are spaced apart along the circumferential direction of the cover main body 1211 and connected to the second opening of the cover main body 1211. One end of the clamping arm 1212 is connected to the outer wall of the cover main body 1211. The clamping arm 1212 and the outer wall of the cover main body 1211 corresponding to the second opening form a receiving groove 124. The edge of the inner tank body 11 corresponding to the inner opening is clamped in the receiving groove 124. The fastening ring 123 is sleeved outside the connecting cover 122, so that the other end of the clamping arm 1212 abuts against the outer wall of the inner tank body 11.

[0060] The inner tank body 11 is provided with a ring-shaped limiting protrusion 114 on the outer side wall near the inner opening, and the free end of the clamping arm 1212 forms a clamping groove 1213. When the fastening ring 123 is sleeved on the outside of the connecting cover 122, the limiting protrusion 114 can be limited and clamped with the clamping groove 1213 of the clamping arm 1212, so that the fastening cover 121 is limited and fixed on the inner tank body 11, and the stable and tight connection between the inner cover body 12 and the inner tank body 11 is ensured.

[0061] In this example, the clamping arm 1212 has elasticity. When clamped, the clamping arm 1212 can generate a pre-tightening force, so that the inner cover body 12 is tightly fitted with the opening of the inner tank body 11. Moreover, through the mechanical cooperation of the clamping arm 1212 and the opening edge of the inner tank body 11, the quick installation and disassembly of the inner cover body 12 can be realized, which can be operated without tools, and the user convenience is improved.

[0062] In addition, the fastening ring 123 is sleeved on the outside of the connecting cover 122, the fastening ring 123 can push the free end of the clamping arm 1212 towards the outer wall of the inner tank body 11, and through the clamping of the limiting protrusion 114 and the clamping groove 1213, a double locking structure of radial limiting combination and axial compression is effectively formed. This kind of setting can prevent the clamping arm 1212 from loosening due to vibration, developing liquid buoyancy or external force, and ensure that the inner cover body 12 always maintains stable connection during development.

[0063] In some embodiments of the present application, the developing inner tank 10 is provided with a fixing member 50. The fixing member 50 includes a mounting shaft 51 and a liquid guiding portion 52 detachably connected to one end of the mounting shaft 51, and the film core 20 is sleeved on the mounting shaft 51. The liquid guiding portion 52 is arranged near the inner opening of the inner tank body 11, and the end of the mounting shaft 51 away from the liquid guiding portion 52 abuts against the inner wall of the inner tank body 11, and the mounting shaft 51 is limited in the limiting groove 113 of the bottom plate 112.

[0064] In this example, the liquid guiding portion 52 is in a funnel structure, the mounting shaft 51 is open at both ends and hollow inside, and the end of the liquid guiding portion 52 is clamped in one end opening of the mounting shaft 51. The developing liquid can enter the developing inner tank 10 through the liquid guiding portion 52 and the inside of the mounting shaft 51.

[0065] The film core 20 is sleeved on the mounting shaft 51, and precise centering is achieved through the gap cooperation between the mounting shaft 51 and the inner hole of the film core 20, so that the film core 20 can rotate or stand still around the axis of the mounting shaft 51 during development, and the coaxiality is ensured, so that the film overlapping or the developing liquid flow is avoided due to eccentric shaking.

[0066] In some examples, a plurality of film cores 20 can be provided, and the plurality of film cores 20 are sequentially sleeved on the outside of the mounting shaft 51 along the axial direction of the mounting shaft 51. Each film core 20 can fix a roll of film, and the plurality of film cores 20 can realize the simultaneous development of multiple rolls of film, thereby improving the development efficiency.

[0067] Further, in the present application, a refrigeration module 40 is arranged in the constant-temperature interlayer 101 between the constant-temperature outer tank 30 and the developing inner tank 10. The refrigeration module 40 can generate cold energy when powered on, and the cold energy generated by the refrigeration module 40 can be transmitted to the developing inner tank 10 through the temperature-conducting medium, so as to reduce the temperature of the developing solution in the developing inner tank 10.

[0068] The temperature-conducting medium has good heat conduction capacity, and the cold energy generated by the refrigeration module 40 can be uniformly transmitted to the outer wall of the developing inner tank 10 through the temperature-conducting medium, so as to avoid local temperature unevenness of the developing inner tank 10, and ensure that the developing solution in the developing inner tank 10 is stably in a low-temperature state.

[0069] In some examples, the refrigeration module 40 can be a semiconductor refrigeration device, which includes a cold face and a hot face. The semiconductor refrigeration device is powered on to generate cold energy on the cold face and heat on the hot face, and the cold face of the semiconductor refrigeration device is used to contact the temperature-conducting medium.

[0070] The semiconductor refrigeration device can be provided in a sheet shape, which has a compact structure and can effectively utilize the limited space of the constant-temperature interlayer 101 between the constant-temperature outer tank 30 and the developing inner tank 10.

[0071] In some embodiments of the present application, the flushing tank 100 can further include a conducting member 60 arranged in the constant-temperature interlayer 101. One end of the conducting member 60 is connected to the cold face of the semiconductor refrigeration device, and the other end of the conducting member 60 is accommodated in the temperature-conducting medium.

[0072] In some examples, the conducting member 60 can be a metal member, such as a copper block, an aluminum plate, or the like. The metal member has a high thermal conductivity, one end of the metal member can be attached to the cold face of the semiconductor refrigeration device, and the other end of the metal member can be directly immersed in the temperature-conducting medium, so as to conduct the heat generated by the cold face of the semiconductor refrigeration device to the temperature-conducting medium, thereby achieving effective conduction of cold energy.

[0073] In some examples, the conducting member 60 can be sapphire glass. The sapphire glass has a high thermal conductivity, which can effectively transmit the cold energy generated by the cold face of the semiconductor refrigeration device to the temperature-conducting medium. In addition, the sapphire glass has extremely strong chemical inertness and cannot exchange ions with the developing solution or the temperature-conducting medium, thereby avoiding pollution of the developing solution.

[0074] In this embodiment, the flushing tank 100 can further include a controller 70 and a temperature probe 80. The controller 70 is electrically connected to the refrigeration module 40, and the controller 70, the refrigeration module 40, and the conducting member 60 can be integrally arranged on the inner cover body 12 of the developing inner tank 10. The temperature probe 80 is arranged in the developing inner tank 10 and can be fixed on the inner cover body 12. The temperature probe 80 is used to measure the temperature of the developing solution and form a temperature signal.

[0075] The controller 70, the refrigeration module 40 and the temperature detector 80 are integrated on the inner cover 12 of the developing inner tank 10 to form an integrated structure module, which is connected with the internal power supply or the external power supply of the washing tank 100 through wires without additional pipelines or complex installation, and the overall structure is compact.

[0076] The temperature detector 80 is electrically connected with the controller 70 to transmit a temperature signal to the controller 70. The controller 70 can control the refrigeration module 40 according to the temperature signal, so as to control the cold quantity generated by the refrigeration module 40.

[0077] In some embodiments of the present application, the washing tank 100 can further include a heating module 90, which includes a heating disc 91 and a heating circuit board 92 electrically connected with the heating disc 91.

[0078] The heating circuit board 92 is arranged in the assembly space formed between the assembly cover 33 and the outer tank body 31 to avoid the contact between the heating circuit board 92 and the temperature-conducting medium. The heating disc 91 is fixed in the inner part of the constant-temperature outer tank 30, and the heating disc 91 can generate heat when powered. The heat generated by the heating disc 91 can be transmitted to the developing inner tank 10 through the temperature-conducting medium to increase the temperature of the developing liquid in the developing inner tank 10.

[0079] Such a setting enables the controller 70 to dynamically adjust the power of the refrigeration module 40 and / or the heating module 90 according to the temperature signal. When the temperature of the developing liquid is higher than a set value, the controller 70 can increase the current passing through the refrigeration module 40 to increase the cold quantity. When the developing liquid with a higher temperature is needed to wash the film, the controller 70 can trigger the heating module 90 to make the heating disc 91 generate heat to increase the temperature of the developing liquid in the developing inner tank 10.

[0080] In some examples, the washing tank 100 can further include a wireless transmission module electrically connected with the controller 70. The wireless transmission module can receive a control signal of an external terminal device and transmit the control signal to the controller 70 to enable the controller 70 to control the refrigeration module 40 and the heating module 90 according to the control signal.

[0081] By arranging the wireless transmission module, the user can remotely operate the washing tank 100, such as starting the washing program, adjusting the temperature set value, pausing / restarting the washing process, etc. In this example, the controller 70 can transmit the temperature signal measured by the temperature detector 80 to the external terminal device through the wireless transmission module.

[0082] The setting enables the terminal device to display the developing liquid temperature, the refrigeration / heating module (40, 90) working state, the remaining time and other parameters in real time, facilitates the user to understand the film developing information in real time, and adjusts accordingly to ensure the quality of the film developing.

[0083] Further, referring to Figure 5 , Figure 6 and Figure 7 , the embodiment also provides a temperature control accessory 200 which can regulate the temperature of the developing liquid in the film developing tank 300. The film developing tank 300 can be an existing tank structure for containing the developing liquid, and the film developing tank 300 can be provided with a film core 20 for fixing the film.

[0084] In this embodiment, the temperature control accessory 200 includes a temperature control outer tank 201 and a refrigeration module 40. The temperature control outer tank 201 is arranged outside the film developing tank 300, and a temperature control interlayer 202 is formed between the temperature control outer tank 201 and the film developing tank 300, which is filled with a temperature conducting medium. The refrigeration module 40 is arranged in the temperature control interlayer 202 and fixed to the temperature control outer tank 201. The refrigeration module 40 can generate cold energy when powered on, and the cold energy generated by the refrigeration module 40 can be transmitted to the film developing tank 300 through the temperature conducting medium, so as to reduce the temperature of the developing liquid in the film developing tank 300.

[0085] The temperature control accessory 200 of the present application does not need to make structural changes to the existing film developing tank 300, and only needs to arrange the temperature control outer tank 201 outside the film developing tank 300 to form a temperature control system, thereby realizing effective compatibility with the main specifications of the film developing tank 300 and reducing the cost of equipment upgrade for the user.

[0086] Moreover, the refrigeration module 40 directly acts on the temperature control interlayer 202, the cold energy transmission path is short and efficient, the temperature of the developing liquid in the film developing tank 300 can be quickly reduced to the target range, and the constant temperature can be maintained by continuous power-on, thereby adapting to the differentiated requirements of different film types on the developing temperature.

[0087] In some examples of this embodiment, the temperature control outer tank 201 includes an accessory tank body 204 and an accessory cover body 205 connected to the accessory tank body 204. The accessory cover body 205 can be screwed on the accessory tank body 204 to realize detachable connection of the accessory cover body 205 and the accessory tank body 204. In other examples, the accessory cover body 205 can also be detachably connected to the accessory tank body 204 by clamping or buckling.

[0088] The temperature control outer tank 201 is arranged outside the film developing tank 300, and a space between the temperature control outer tank 201 and the film developing tank 300 forms a temperature control interlayer 202 filled with a temperature conducting medium. The temperature conducting medium can be water, ethylene glycol solution, heat conducting oil, silicone oil, molten salt, air, etc., which is not limited here.

[0089] Further, the refrigeration module 40 can be arranged on the accessory cover 205 or on the inner wall of the accessory tank 204.

[0090] The refrigeration module 40 in the temperature control accessory 200 is consistent with the structure and function of the refrigeration module 40 in the above embodiment, which can be a semiconductor refrigeration device including a cold face and a hot face. The semiconductor refrigeration device is powered to generate cold on the cold face and heat on the hot face, and the cold face of the semiconductor refrigeration device is used to contact the temperature conducting medium.

[0091] In some examples, the temperature control accessory 200 can further include a temperature probe 80. The temperature probe 80 is arranged on the accessory cover and is used to measure the temperature of the developing solution to form a temperature signal. The end cover 301 of the film developing tank 300 is provided with a perforation 302, and when the temperature control accessory 200 is used with the film developing tank 300, the temperature probe 80 can extend into the inside of the film developing tank 300 through the perforation to measure the temperature of the developing solution in the film developing tank 300.

[0092] In this example, the temperature control accessory 200 can further include a controller (not shown in the figure). The controller is electrically connected with the temperature probe 80 and the refrigeration module 40. The temperature probe 80 is electrically connected with the controller to transmit the temperature signal to the controller. The controller can control the refrigeration module 40 according to the temperature signal to control the cold generated by the refrigeration module.

[0093] The controller, the refrigeration module 40 and the temperature probe 80 can be integrally arranged on the accessory cover 205 to form an integrated structure module, which is connected with the internal power supply or external power supply of the temperature control accessory through wires without additional pipelines or complex installation, and the overall structure is more compact.

[0094] In this example, the temperature control accessory can further include a conducting member 60. The conducting member 60 is arranged in the temperature control interlayer 202. One end of the conducting member 60 is connected with the cold face of the semiconductor refrigeration device, and the other end of the conducting member 60 is accommodated in the temperature conducting medium in the temperature control interlayer 202.

[0095] The conducting member 60 can be a metal member, such as a copper block, an aluminum plate, or the like. The metal member has a high thermal conductivity, one end of the metal member can be attached to the cold surface of the semiconductor refrigeration member, and the other end can be directly immersed in the temperature-conducting medium, so as to conduct the heat generated by the cold surface of the semiconductor refrigeration member to the temperature-conducting medium, thereby achieving effective conduction of cold. In other examples, the conducting member 60 can be sapphire glass. The sapphire glass has a high thermal conductivity and can effectively transfer the cold generated by the cold surface of the semiconductor refrigeration member to the temperature-conducting medium. Moreover, the sapphire glass is extremely inert chemically and will not ion exchange with the developing solution or the temperature-conducting medium, thereby avoiding contamination of the developing solution.

[0096] Further, in the present embodiment, the accessory cover 205 can include an outer cover portion 2051 and an inner cover portion 2052. The inner cover portion 2052 is arranged inside the outer cover portion 2051, which is used to be detachably connected to the accessory tank body 204. An installation layer 2053 is formed between the inner cover portion 2052 and the outer cover portion 2051, and the controller and the refrigeration module 40 can be arranged in the installation layer 2053, and the temperature probe 80 can be arranged on the inner cover portion 2052. The refrigeration module 40 arranged in the installation layer 2053 can be connected to the conducting member 60 to transfer cold to the temperature-conducting medium through the conducting member 60.

[0097] When the temperature-controlled accessory 200 is used with the film developing tank 300, the accessory cover 205 is connected to the accessory tank body 204, and the inner cover portion 2052 can seal the opening of the film developing tank 300, thereby achieving sealing of the film developing tank 300. In this example, the film developing tank 300 can cancel the arrangement of the conventional end cover 301, and the inner cover portion 2052 is used to achieve fastening and sealing, thereby simplifying the overall structure.

[0098] In addition, the bottom of the temperature-controlled outer tank 201 can be provided with a heating disc 91. The heating disc 91 can generate heat when powered on, and the heat generated by the heating disc 91 can be transferred to the film developing tank 300 through the temperature-conducting medium, so as to increase the temperature of the developing solution in the film developing tank 300.

[0099] For the present application, the refrigeration module can directly act on the temperature-conducting medium in the constant-temperature layer to transfer cold to the developing inner tank or the film developing tank to quickly reduce the temperature of the developing solution, thereby breaking through the limitation that the conventional developing solution needs to rely on a refrigerator for cooling. Moreover, the temperature-conducting medium in the constant-temperature layer uniformly transfers cold through heat conduction, thereby avoiding local temperature deviation of the developing inner tank or the film developing tank, ensuring that the film contacts the temperature-uniform developing solution, reducing uneven development caused by temperature difference, and improving the consistency of the washing quality. In addition, the refrigeration module arranged in the constant-temperature layer can maintain the developing solution at a target low temperature, thereby solving the problem that the low-temperature state of the developing solution is difficult to control in a high ambient temperature environment, and effectively ensuring the quality of film washing.

As mentioned above, the present application is capable of taking many forms of implementation and being practiced in various ways, and the above description is not intended to limit the application in any way, except as required by the appended claims and their equivalents.
