DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a wet color electrophotographic copying machine (hereinafter referred to as a copying machine) which is a wet image forming apparatus will be described below. FIG. 1A is a front view showing a schematic configuration of the inside of a copying machine according to the present embodiment, and FIG. 1B is a diagram showing the internal structure of a carrier liquid vapor recovery device main body disposed on the right side of the copying machine. It is a right view shown. This copying machine has a plurality of photoconductors 10 corresponding to a plurality of colors, forms an electrostatic latent image on each photoconductor surface by electrophotography, and develops the electrostatic latent image by a wet developing unit 11. And
After being transferred onto a transfer sheet and fixed by a fixing unit having a pair of heat rollers 12, the sheet is discharged to a sheet discharge unit having a sheet discharge tray 13 to form a color copy. Here, the developing unit uses a developing solution in which the toner is dispersed in a solvent as a carrier liquid.
As the solvent, an organic solvent such as an isoparaffin-based solvent having a high volume resistivity, for example, Isopar (trade name) manufactured by Exxon is generally used. The illustrated copying machine uses a transport belt 14 to transport the transfer paper so as to sequentially face the plurality of photoconductors.

The carrier liquid vapor recovery device of this copying machine
The fixing portion and at yield Atsumarishitsu 21 formed covered by a cover member 20 so that as much as possible sealed the paper discharge unit, advance confine the carrier liquid vapor generated by fusing operation, the collection chamber 21 The air containing the carrier liquid vapor is connected to the exhaust port 22, and the suction fan 25 passes through a first duct section 23 inclined so as to become lower toward the downstream side of the air flow, and a liquefaction section 24 provided at the end of the duct section. To aspirate. Carrier liquid vapor contained in air passing through the liquefaction unit 24 as described in detail later, water vapor from transfer paper,
And it liquefies the moisture originally contained in the air. The air blown from the suction fan 25 after receiving the liquefaction process passes through the second duct portion 26 for guiding the air along the outer wall of the first duct 23, and via the auxiliary exhaust fan 27 installed as necessary. Exhaust outside the machine.

The carrier liquefied in the liquefaction section
The liquid and water flow under their own weight into the liquid receiver 30 of the carrier liquid / water separation unit 29 provided below through the downflow port 28 provided on the bottom wall of the liquefaction unit 24. This separation unit 2
At 9, the carrier liquid and water are separated as described later in detail, and stored in storage tanks 31 and 32, respectively. This cap
The carrier liquid stored in the rear liquid storage tank 31 can be reused in the developing section 11 and the cleaning section of the copying machine main body.

The liquefaction unit 24 performs a liquefaction process by cooling. For this cooling, a fin ever having a plurality of fins 33 is provided above the downflow port 28 in the liquefaction unit, and the fin ever is connected to a compressor 34 by a refrigerant pipe 35. FIG. 2 is an explanatory diagram of the connection relationship. The fin ever, as shown in FIG.
3 is preferably provided so as to be parallel to the flow of the airflow A generated by the suction fan 25.

In the liquefaction unit 24, the air containing the carrier liquid vapor which has been air-cooled to some extent in the first duct unit 23 is cooled using a refrigerant to a temperature at which the carrier liquid and water can be sufficiently liquefied. As a result, the carrier liquid or the like adheres as droplets to the fins 33 and the inner wall surface of the liquefier, and is collected in the flow-down port 28 by its own weight. Here, in this embodiment the fan 25 because it is in the arrangement of the air flow direction downstream side of the fin group of the fin EVA, as compared with the case of the arrangement of the air flow direction improves downstream Conversely, increasing the cooling effect I can do it. FIG.
(A) is an explanatory view of an airflow when the arrangement is reverse to that of the present example for comparison. As you can see from this figure,
Since the blowout of the fan 25 is performed in a cross section corresponding to the diameter of the fan, the airflow becomes insufficient at the peripheral portion of the fin 33 of the fin ever. On the other hand, in this example, FIG.
As shown in FIG.
Therefore, the airflow along the inner wall of the first duct portion 23 can be effectively brought into contact with the peripheral edge of the fin 33.

Further, since the suction fan 25 is disposed downstream of the liquefaction unit 24 in the airflow direction, the blades of the fan, which are constituent members located in the airflow path of the airflow generation device, are controlled by the liquefaction unit 24. The liquefaction causes the carrier liquid or the like to come into contact with the airflow. Therefore, compared with the case where the suction fan 25 is provided on the upstream side in the airflow direction from the liquefaction unit 25,
Less condensation such as carrier liquid on the surface of the above constituent members,
Efficient carrier liquid transport using an airflow from the airflow outlet 22 of the collection chamber 21 to the liquefaction unit 25 is enabled.

As described above, the air from the collection chamber 21 is air-cooled in the first duct 23,
Liquefied droplets, particularly water droplets that are easily liquefied, also adhere to the inner wall surface of the substrate. Such droplets flow down by their own weight along the bottom wall surface of the first duct portion 23 inclined so as to become lower toward the downstream in the airflow direction, and quickly collect on the liquefaction portion 24 side. In addition, the air discharged to the outside through the liquefaction unit 24 is supplied to the first duct unit 2.
Since the air is passed through the second duct portion 26 along the outer wall of No. 3, preliminary cooling and liquefaction of the air by the first duct portion 23 can be promoted. As a result, the size of the cooling device using the refrigerant can be reduced.

It is desirable that the inner surface of the first duct portion 23 and the members forming the collecting chamber 21 be made of a resin or a non-rusting metal (aluminum, stainless steel, etc.) in order to prevent rust by water droplets. . In addition, in order to make the droplet easily move by its own weight, it is desirable to perform a water-repellent treatment on the inner wall surface.

Further, it is desirable to perform an oil-repellent treatment on the fins 33 in order to make it difficult to wet a part or the whole of the fins 33 with the carrier liquid . Examples of the oil repellent include tetrafluoroethylene, trifluoride ethylene, vinylidene fluoride, tetrafluoroethylene-6-fluoropropylene copolymer, IH-pentadecafluorooctyl methacrylate, perfluorinated lauric acid , Vinyl chloride, perfluorinated alcohols, perfluoroalkyl ester polymers, fluorinated hydroxy unsaturated esters, and the like. If such an oil repellent is applied to form an oil repellent coating layer, the carrier liquid can be repelled by the layer. The method for applying the oil repellent may be a method suitable for the oil repellent used here. For example, in the case of IH-pentadecafluorooctyl methacrylate, it is only necessary to dilute with a volatile solvent and spray with a spray. In this case, a coating layer is formed as the solvent evaporates.

As described above, at least a part of the surface of the fin 33 is formed of a material that is not easily wetted by the carrier liquid , so that the surface of the fin 33 is spaced from the surface of another member (such as the adjacent fin 33). Also in the case of the structure facing the fin, the gap is partially filled with the vapor droplets adhered to the fin surface, so that the passage of the air flow is not hindered. Therefore, the liquefaction effect by cooling can be stably exhibited over time.

The separating section 29 separates the water and the carrier liquid by utilizing the specific gravity difference between the water and the carrier liquid (for example, the specific gravity of the isoparaffinic organic solvent is 0.7 to 0.8 with respect to water).
For this separation, as shown in FIG. 4, a liquid receiver 30 having an opening at the top and having an overflow port 30a on the side wall.
The overflow liquid guide member 40 which covers the overflow port 30a from the outside, receives the liquid overflowing from the outside, and guides the liquid to the carrier liquid storage tank 31.
A liquid outlet 30b of the liquid container 30 formed at a position lower than the overflow port 30a and a water storage tank 32.
And a drain pipe 41 that connects

The drain pipe 41 is arranged such that the uppermost position 41a of the inner bottom wall at the end on the water storage tank side coincides with the overflow liquid level H determined by the lower end position of the overflow port 30a. The pipe portion between the outlet and the liquid receiver drain port 30b is lower than the overflow liquid level H. An opening / closing valve 42, which is set by the tank 32 and is operated by a collar 32a at a liquid receiving port of the tank, is provided at the opening on the side of the water storage tank 32. Further, a sensor 43 for detecting the set state of the tank 32 is provided. At the water storage tank side end, a water injection port 50 is formed so that the opening is higher than the uppermost position. A holder 52 for holding a filter 51 for preventing dust from passing through the water injection opening 50 is inserted into the pipe. Such a filter 51 for preventing the passage of dust may be provided at another location of the pipe, for example, at an end opening on the water storage tank side.

The overflow port 30a has a hole diameter of 2
A mesh 44 that is in the range of 0 μm to 200 μm is filled. The mesh 44 has a property of allowing the carrier liquid to pass therethrough and not allowing water to pass therethrough. Such mesh 44, may be available for separation of the carrier liquid and the water of the developing solution is believed to be due to the difference in wettability to the carrier liquid and the mesh 44 with water. As the material of the mesh, stainless steel, nylon, polyester, polyethylene, polypropylene, tetron, glass, fluororesin and the like are favorable. Further, the mesh 44 is formed by, for example, as shown in FIGS. 5A and 5B, a portion 45 of the peripheral wall of the liquid receiver 30 where the overflow port is formed, and a portion below the portion 45. It is desirable to be configured so that it can be easily detached by using it as a holder member.

In the present embodiment, the outlet 2 of the liquefaction unit 24
A chain whose upper end is attached to the structure of the liquefaction section 24 so that the liquid can flow smoothly from 8 to the liquid level in the liquid receiver 30, and the freely movable lower end reaches below the overflow liquid H. 51 are provided.

In the above separating section 29, water is injected from the water inlet 50 into the intermediate portion located lower than the overflow liquid level H of the drain pipe 41 at the time of installation of the apparatus, and the water is previously injected into the liquid receiver 30. This water is made to enter, and the water level is set to a water level slightly lower than the overflow liquid level H.
In this state, the carry through the downflow port 28 of the liquefaction unit 24 is carried out.
The liquid mixture of the liquid A and the water is received by the liquid receiver 30. The mixed liquid received in the container is separated in the container 30 by specific gravity.
Separate so that the liquid layer of the carrier liquid is on top. And
Carry overflow liquid level above H carrier liquid liquid layer
The liquid A overflows from the overflow port, passes through the overflow liquid guide member 40, and is stored in the carrier liquid storage tank 31. Acceptance of the liquid from such liquefaction unit 24, separation of the carrier liquid and water by the difference in specific gravity, while etc. overflow separated carrier liquid is happening across the intermediate portion of the drain pipe 41, Eki受Container 3
0 side and the uppermost position 41a at the end of the drain pipe 41
The liquid level tries to balance with the side. That is, when the amount of liquid in the liquid receiver 30 increases, the liquid level at the end of the drain pipe 41 on the water storage tank side also tends to increase. However, the uppermost position 41a at this end is an overflow position toward the water storage tank, and the water that is going to exceed this overflows and is stored in the water storage tank. Moreover, the uppermost position 41a matches the overflow liquid level in the liquid receiver 30. As a result, the liquid level in the liquid receiver 30 is substantially maintained at the overflow liquid level, and only the liquid layer of the carrier liquid formed by the separation due to the specific gravity difference in the liquid receiver 30 faces the overflow port 30a. Will be maintained.

Then, for some reason, the liquid receiver 3
Even when the water level in 0 (the position of the interface between the carrier liquid and the water) exceeds the overflow liquid level H, the overflow of water is prevented by the mesh 44, so that the water in the carrier liquid storage tank is prevented. Water can be reliably prevented from entering. Note that the interface between the carrier liquid and water in the liquid receiver is higher than the overflow liquid level by positively utilizing the permeation function of the mesh 44 so that the uppermost part of the end of the drain pipe 41 can be used. position 41a may be set.

Further, the liquid falling from the downflow port 28 of the liquefaction section 24 flows down the chain 51 gently and reaches the liquid pool in the liquid receiver 30, so that the liquid pool flows through the downflow port 28. Unlike the case where the liquid drops directly, the bubbles are less likely to be generated in the liquid pool, and the specific gravity difference in the liquid pool allows the carrier liquid and the water to be separated quickly. Furthermore, this chain 5
1, free end are the deformable, for example, can the liquid receiver 30 and detachably composed within the device, does not obstruct the desorption operation.

It should be noted that the drain pipe 41 is
The water level (the position of the interface between the carrier liquid and the water) reaches the level L at which the water in the inside evaporates and the space between the liquid receiver side and the water storage tank side communicates with each other across the bottom of the drain pipe 41. When it drops, the liquefaction unit 2 is operated by the subsequent carrier liquid recovery operation.
The carrier liquid received from 4 enters the water storage tank 32 side from the lowermost part of the drain pipe 41. The carrier liquid rises due to the subsequent reception of water from the liquefaction unit 24 and the water storage tank 32
It rises inside the drain pipe 41 on the side and eventually mixes into the water storage tank 32. In order to prevent such a situation, as shown in FIG. 5 (c), it has an outer shape that can fit into the drain port of the liquid receiver 30, and has a specific gravity between the carrier liquid and water. It is desirable that the floating plug member 46 having the same be put in the liquid receiver 30.

Due to the setting of the specific gravity, the floating plug member 46 cannot be floated so as not to contact the bottom of the liquid receiver 30 with the buoyancy of only the carrier liquid . Therefore, at least a part of the liquid outlet 30 is immersed in the liquid layer of the water, and falls with the decrease of the water level in the liquid receiver 30. The drain port is sealed by fitting into the portion 30b . Even if the water level in the drain pipe 41 drops after the drain port is sealed in this way, the carrier liquid remaining in the liquid receiver 30 cannot pass through the drain port. Thereby, the above-mentioned problems can be prevented.

By using such a floating plug member 46, when the floating plug member 46 is fitted into the discharge port, a state in which the carrier liquid does not enter at all below the fitting portion between the two. If this is to be achieved reliably, part of the buoy member 46 will be submerged in the liquid layer of water and the remaining part will be completely captive.
Rear fluid liquid layer state submerged in (this state, the volume of the floating plug member 46 is minimized submerged in the liquid layer), the equivalent to the interface of the two liquid layers in the floating plug portion <br/> member higher than the position to position is such that the fitting position between the outlet portion 30b, it is desirable to set the specific gravity of the shape and floating plug member of the outlet portion and the float stopper member.

Further, for example, in the illustrated example, the float member 46 is formed in a spherical shape so as to be fitted to the funnel-shaped liquid receiver discharge port, but a weight or the like is built in a position off the center of the inside. For example, when restricting the floating posture, the external part to be fitted to the discharge port may be formed into a shape capable of fitting to the discharge port.

In order to prevent the water in the drain pipe 41 from spoiling and generating an odor,
An ultraviolet irradiation device for sterilizing the water in 41 may be provided, or a preservative may be mixed into the water at the time of this water injection. In the case where ultraviolet irradiation is performed from outside the pipe, at least the irradiated portion of the drain pipe 41 is formed of a material that can pass ultraviolet light.

Further, a sensor 60 (see FIG. 4) for detecting the water level in the water storage tank 32 is provided, a signal is generated when the tank is full, and a display device is driven by using this signal, and an image forming apparatus is used. Alternatively, it is desirable to stop the operation of the carrier liquid vapor recovery device.

Further, a sensor for detecting the liquid level in the liquid receiver 30 is provided, and when the liquid level reaches a predetermined liquid level, for example, a liquid level at which there is a possibility of liquid leaking out of the liquid receiver 30, It is desirable to stop the copying operation and the carrier liquid collecting operation.

It is desirable to float a sheet made of a lipophilic material on the water surface in the water storage tank 32 so that the carrier liquid mixed in the water storage tank 32 for some reason is adsorbed. As the lipophilic sheet material, a water-repellent, lipophilic sheet, for example, a non-woven sheet made of polyethylene fiber or polypropylene fiber can be used.

Further, a drain 62 (see FIG. 4) for discharging the liquid may be provided to be connected to a lower portion of the carrier liquid storage tank 31, or a similar drain may be provided to the water storage tank 32. Instead of or in addition to providing such a drain 62, a pump for pumping liquid may be provided in these tanks 31, 32.

Further, the upper part itself in the water storage tank 32 or the other end of the communication pipe having one end connected to the water storage tank 32 is opened to the outside of the copying machine, and the water vapor evaporates in the tank to constantly remove water vapor from the apparatus. It may be possible to release it. In this case, a heater or an ultrasonic vibration device for heating the water in the water storage tank 32 may be provided to promote the evaporation.

The radiator 63 of the compressor 34
(See FIG. 4) may be cooled by the water in the water storage tank 32.

Further, a sensor 61 (see FIG. 4) for detecting the liquid level is provided in the carrier liquid storage tank 31 to generate a signal when the tank is full. It is desirable to stop the operation of the forming device or the carrier liquid vapor recovery device.

Further, the inner surface of the carrier liquid storage tank 31 and the water storage tank 32 and the liquid contact portion of the member forming the separating portion 24 are made of a material which is hardly rusted, for example, a resin or a non-rusting metal (aluminum, stainless steel). Such)
It is desirable to form with.

Due to movement or the floor inclination of the installation location.
Water flows through the opening toward the carrier liquid storage section after separation.
And it can be prevented from being discharged together with the carrier liquid.

[0060] In particular, Oite the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to claim 1, the interface position between the carrier liquid and water separated by the specific gravity difference between each other in the liquid receiving chamber, the liquid receiving chamber maintained at the interface maintaining means so that a constant surface position lower than the carrier liquid overflow port formed in the side wall, only the carrier liquid having a smaller specific gravity than water to overflow from the overflow port, to extract the carrier liquid only. Thus, the above liquid receiving

And the liquid receiving chamber
Of carrier liquid and water separated from each other by
The height of the interface is lower than the overflow port

By the formation, only the carrier liquid can be extracted. Therefore, the overflow port is connected to the carrier liquid storage tank to store the carrier liquid in the carrier liquid storage tank, or the overflow port is connected to the developer tank and the like to directly send the carrier liquid to the developer tank and the like. Thus, the carrier liquid can be reused.

According to the carrier liquid vapor recovery apparatus in the wet image forming apparatus of the first aspect , the separation member provided at the overflow port allows only the carrier liquid to pass without passing water, so that the apparatus can be temporarily operated. Even when the interface is higher than the overflow port due to a certain degree of vibration or a certain level of inclination of the floor of the installation place, it is possible to prevent water from being discharged together with the carrier liquid through the overflow port.

[0062] Further, according to the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to claim 2, certain size of dust entrained like carrier liquid to the mesh as the separator member, through an overflow together with a carrier liquid Can be prevented from being discharged. Therefore, it is possible to prevent such dust from being mixed in the carrier liquid to be reused.

[0063] Furthermore, according according to the carrier liquid vapor recovery apparatus in the wet image forming apparatus of claim 3, the separation member because it is detachable from the liquid receiving chamber, for example, clogging of the mesh claim 1 Thereby, handling when replacing or cleaning the mesh as the separating member is easy.

Further, in the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to the fourth aspect , a large amount of carrier liquid exceeding the performance of the interface position maintaining means is transferred from the liquefying means to the liquid receiving chamber at one time. When the interface between the carrier liquid and water separated from each other drops to the vicinity of the water discharge port at the bottom of the liquid receiving chamber, the specific gravity of the carrier liquid and water is intermediate with the decrease in the interface. The buoy descends and fits into the edge of the water outlet. Therefore, even when such a decrease in the interface occurs, the carrier liquid is not discharged from the discharge port of the liquid receiving chamber, and the carrier liquid is stored in the water tank that stores the water for exhaust together with the water. It is possible to prevent such a situation.

[0065] Further, in the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to claim 5, when the device is installed,

The water that flows into
The process is performed until the water level in the liquid receiving chamber matches a predetermined interface position to be maintained. As described above, when the water level in the liquid receiving chamber coincides with the predetermined interface position, the end of the communication pipe set at a height corresponding to the predetermined interface position also has a height from the intermediate portion side. Water reaches. In this initial state, when the carrier liquid vapor recovery operation is performed along with the image forming operation of the wet image forming apparatus, the liquid from the liquefying unit is received in the liquid receiving chamber. The received liquid is separated into a carrier liquid and water by a difference in specific gravity, and after the separation, the carrier liquid located above overflows from the overflow port.
On the other hand, by the weight of the carrier liquid and the separated water temporarily staying in the liquid receiving chamber to overflow as described above,
A part of the water filled in the intermediate portion or the like is pushed to the opposite side of the communication pipe from the liquid receiving chamber, and overflows from the end. Therefore, a water storage tank for storing water overflowing from the end portion or a drain for draining water outside the image forming apparatus is connected to the end portion of the communication tube further from the end portion. By doing so, only the water after separation can be taken out. here,
By receiving the liquid from the liquefaction means, the water level (the height of the interface between the carrier liquid and the water) in the liquid receiving chamber, which temporarily rises only by the moisture contained in the liquid, becomes higher than the overflow port of the liquid receiving chamber. The overflow capacity is set in accordance with the structure of the overflow port or the like so that the carrier liquid is discharged from the overflow port before the pressure drops. As a result, the separated carrier liquid overflows from the end of the water communication pipe at the middle of the communication pipe with the weight of water having a height equal to or higher than the overflow port remaining in the liquid receiving chamber after being discharged from the overflow port. Subsequently, when the overflow ends, the water level in the liquid receiving chamber coincides with the end. That is, the water level in the liquid receiving chamber coincides with the predetermined interface position. The overflow of the carrier liquid from the overflow port of the liquid receiving chamber and the overflow of water from the end of the communication pipe are as follows.
It occurs continuously each time a liquid is received from the liquefaction means, whereby the interface in the liquid receiving chamber is maintained at a predetermined interface. As described above, according to the carrier liquid vapor recovery apparatus in the wet type image forming apparatus of the fifth aspect , since the interface position maintaining means is constituted by using a simple structure of the communication pipe having a predetermined structure, the apparatus can be miniaturized. Is advantageous.

Conversely, the evaporation of water in the water storage tank can be promoted, and the trouble of taking out the tank from the device and discarding the water can be eliminated or the frequency can be reduced.

[0075] Particularly, according to the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to claim 15, storing the carrier liquid separated by the separating means to the carrier liquid storage tank. Then, the liquid level in the tank is detected by a liquid level detector, and a signal is generated by signal generating means as necessary based on the detection result of the detector. For example, a signal is generated when the tank is full, and this signal is used to drive the display device or stop the operation of the image forming device or the carrier liquid vapor recovery device. According to this, it is possible to prevent the carrier from leaking from the tank. Also, the operation of the pump and the like according to claim 16 described later can be controlled by the signal from the signal generating means.

[0076] Further, according to the carrier liquid vapor recovery apparatus in the wet image forming apparatus according to claim 16, from the carrier liquid storage tank, it is possible to take out the liquid with a drain for liquid discharge.
