Description

  The present invention relates to a tank that can be refilled with liquid through an inlet.

  Conventionally, a tank that can be replenished with liquid through an inlet is known. Further, for example, Patent Document 1 discloses an ink tank in which a viewing surface that can visually recognize ink in an ink chamber and a scale indicating the amount of ink in the ink chamber are formed below the injection port. In the ink tank having the above configuration, the user may inject ink into the ink chamber through the injection port until the liquid level of the ink visually recognized through the viewing surface reaches the position of the maximum scale.

JP 2014-37058 A

  However, when ink spilled from the injection port during ink injection adheres to the viewing surface or scale, there is a problem that the visibility of the viewing surface or scale decreases. In particular, since the ink tank described in Patent Document 1 is provided with a damming portion that dams up ink spilled from the inlet, the ink overflowing from the damming portion is provided with a viewing surface or scale. There is a possibility of extensive contamination of the area.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a liquid consuming apparatus and an ink tank in which a decrease in visibility inside a tank capable of injecting liquid from an injection port is suppressed. .

  The liquid consuming device according to the present invention includes a liquid storage chamber in which liquid is stored, a standing wall that defines one end of the liquid storage chamber in a first direction that intersects the vertical direction, and the liquid in the liquid storage chamber is visible from the outside. And a tank having an inlet penetrating the standing wall for injecting liquid into the liquid storage chamber, a liquid consuming part for consuming the liquid stored in the liquid storage chamber, and the standing wall in the first direction And a cover that covers the upright wall. The cover includes a non-permeable portion that makes a region including a virtual line passing through a lower end of the inlet and extending vertically in the standing wall invisible from the outside of the liquid consuming device, and the standing wall. A region that is shifted in the vertical direction and the second direction orthogonal to the first direction with respect to the imaginary line is visible from the outside of the liquid consuming device.

  The liquid spilled from the inlet in the tank configured as described above contaminates the standing wall along the virtual line. Therefore, by making the portion facing the standing wall region including the imaginary line out of the cover covering the standing wall a non-transmissive portion and the portion facing the standing wall region shifted in the second direction from the imaginary line as the transmissive portion. And it can suppress that the visibility inside a liquid storage chamber falls, and can make the contamination of the standing wall by a liquid inconspicuous.

  A tank according to an aspect of the present invention includes a liquid storage chamber in which a liquid to be supplied to a liquid consumption unit is stored, a standing wall that defines one end of the liquid storage chamber in a first direction that intersects the vertical direction, and the liquid In order to inject liquid into the storage chamber, an injection port penetrating the standing wall is provided. The standing wall is erected along the vertical direction and the liquid in the liquid storage chamber is visible from the outside, and the upper end of the base wall is continuous with the base wall and inclined toward the liquid storage chamber. And an inclined wall. The inlet is provided in the inclined wall. The outer surface of the inclined wall facing the outside of the tank is monotonously inclined toward the liquid storage chamber toward the upper side between the inlet and the base wall. The base wall is stored in the liquid storage chamber at a position shifted in a vertical direction and a second direction orthogonal to the first direction with respect to a virtual line passing through the lower end of the inlet and extending in the vertical direction. An instruction unit indicating information on the liquid is provided.

  According to the said structure, it can suppress that an indicator is contaminated with the liquid which spilled from the inlet. As a result, it is possible to suppress a decrease in the visibility inside the liquid storage chamber at the position of the instruction unit. Note that “the base wall and the inclined wall are continuous” means that no other component (for example, a protrusion, a rib, a groove, or a depression) is provided between the base wall and the standing wall. Further, “inclining monotonously toward the liquid storage chamber toward the upper side” is not limited to the fact that the inclination angle of the outer surface of the inclined wall is constant.

  For example, the outer surface of the inclined surface includes a first surface, a second surface, and a third surface having different inclination angles, the second surface is farther from the base wall than the first surface, and the third surface is the base wall from the second surface. In the case where the connection position between the first surface and the second surface is lower than the connection position between the second surface and the third surface, the connection position between the first surface and the second surface is the second surface. And it is excluded that it is located above the connection position of the third surface. That is, in the present embodiment, the connection positions of the plurality of surfaces having different inclination angles are positioned higher as they are separated from the base wall.

  More preferably, when the outer surface of the inclined wall is configured by a plurality of surfaces having different inclination angles, the upper surface is allowed to have an inclination angle closer to the horizontal direction than the lower surface. It is excluded that the surface has an inclination angle closer to the vertical direction than the lower surface. That is, on the outer surface of the standing wall extending from the inlet to the base wall, a ridge is formed at the boundary between two surfaces adjacent in the vertical direction, and no valley is formed. As a result, the outer surface of the inclined wall between the injection port and the base wall does not have a shape such as a protrusion, a rib, a groove, or a depression that can become a liquid pool in which liquid spilled from the injection port is accumulated.

  A tank according to another aspect of the present invention includes a liquid storage chamber in which a liquid to be supplied to a liquid consumption unit is stored, a standing wall that defines one end of the liquid storage chamber in a first direction that intersects the vertical direction, and the above In order to inject liquid into the liquid storage chamber, an injection port penetrating the standing wall is provided. The standing wall includes a non-permeating portion that makes the liquid in the liquid storage chamber invisible from the outside of the tank in a region including a virtual line that passes through the lower end of the inlet and extends in the vertical direction, and the virtual line. On the other hand, it has the permeation | transmission part which makes the liquid in the said liquid storage chamber visible from the exterior of this tank in the area | region which shifted | deviated to the 2nd direction orthogonal to the perpendicular direction and said 1st direction.

  According to the said structure, it can suppress that a permeation | transmission part is contaminated with the liquid which spilled from the injection hole. As a result, it is possible to suppress a decrease in visibility inside the liquid storage chamber through the transmission part.

  According to the present invention, of the cover covering the standing wall, a portion facing the standing wall region including the imaginary line is a non-transmissive portion, and a portion facing the standing wall region shifted in the second direction from the imaginary line is the transmissive portion. By doing so, it is possible to prevent the visibility inside the liquid storage chamber from being lowered, and it is possible to make the standing wall contaminated with liquid inconspicuous.

As shown in FIG. 2, the recording unit 24 is disposed between the conveyance roller unit 54 and the discharge roller unit 55 in the conveyance direction 16. The recording unit 24 is disposed so as to face the platen 42 in the up and down direction 7 with the conveyance path 65 interposed therebetween. That is, the recording unit 24 is disposed above the transport path 65 in the vertical direction 7 and at a position facing the transport path 65. The recording unit 24 includes a carriage 23 and a recording head 39 (an example of a head or a liquid consumption unit).

  As shown in FIG. 3, the carriage 23 is supported by guide rails 43 and 44 that extend in the left-right direction 9 at positions spaced in the front-rear direction 8. The guide rails 43 and 44 are supported by the frame of the printer unit 11. The carriage 23 is connected to a known belt mechanism provided on the guide rail 44. This belt mechanism is driven by a carriage motor (not shown). That is, the carriage 23 connected to the belt mechanism reciprocates in the left-right direction 9 by driving the carriage motor. The movement range of the carriage 23 extends from the conveyance path 65 to the right and left in the left-right direction 9 as indicated by the one-dot chain line in FIG.

As shown in FIGS. 2 and 3, the platen 42 is disposed between the transport roller unit 54 and the discharge roller unit 55 in the transport direction 16. The platen 42 is disposed so as to face the recording unit 24 in the vertical direction 7 and supports the paper 12 conveyed by the conveyance roller unit 54 from below.

[Ink tank 100]
As shown in FIG. 1, the ink tank 100 is accommodated in the multifunction machine 10. The ink tank 100 is fixed to the multifunction device 10 so that it cannot be easily removed from the multifunction device 10. More specifically, the ink tank 100 is accommodated in the multifunction peripheral 10 through an opening 22 formed on the front surface of the casing of the multifunction peripheral 10 and at the right end in the left-right direction 9. The opening 22 is adjacent to the opening 13 in the left-right direction 9. However, the front surface of the ink tank 100 (a part of a base wall 101A and an inclined wall 101B described later) is in front of the opening 22 in the front-rear direction 8 (more specifically, in front of the front wall of the casing that defines the opening 22). To position. The casing of the multifunction machine 10 has a support surface 28 (see FIG. 10) located inside the opening 22 and below the ink tank 100. The ink tank 100 is supported on the support surface 28.

  The multifunction machine 10 is provided with a box-shaped cover 70 that can cover the front surface of the ink tank 100 positioned in front of the opening 22. The cover 70 covers the opening 22 and the front wall 101 of the ink tank 100 (see FIG. 1A), and the exposure position (exposes the opening 22 and the front wall 101 of the ink tank 100 to the outside of the multifunction machine 10). It is supported by the casing of the multi-function device 10 so as to be rotatable between FIG. As shown in FIGS. 10 and 11, the cover 70 is supported by the casing of the multifunction machine 10 so as to be rotatable around a rotation shaft 71 extending in the left-right direction 9 on the lower end side in the vertical direction 7. The rotation shaft 71 in the present embodiment is located in front of the front wall 101 in the front-rear direction 8 (that is, on the opposite side of the ink chamber 111 with respect to the front wall 101) and below the ink tank 100 in the vertical direction 7. .

  As shown in FIGS. 4 and 5, the ink tank 100 has a substantially rectangular parallelepiped outer shape. The ink tank 100 includes a front wall 101, a right wall 102, a left wall 103, an upper wall 104, and a lower wall 105. On the other hand, the rear surface of the ink tank 100 is open. The film 106 is welded to the rear end surfaces of the right wall 102, the left wall 103, the upper wall 104, and the lower wall 105, whereby the rear surface of the ink tank 100 is sealed. That is, the film 106 forms the rear wall of the ink tank 100. The ink tank 100 having the above configuration is integrally formed by, for example, injection molding of a resin material. For example, the internal shape of the ink tank 100 to be described later is defined by a mold (not shown) that is pulled backward from the opened rear surface of the ink tank 100.

  The upper wall 104 defines the upper end of the ink chamber 111 in the vertical direction 7. The lower wall 105 defines the lower end of the ink chamber 111 in the vertical direction 7. The front wall 101, the right wall 102, and the left wall 103, which are examples of standing walls, are erected between the upper wall 104 and the lower wall 105 so as to intersect the upper wall 104 and the lower wall 105. Each of the walls 101 to 105 has at least translucency so that the ink in the ink chamber 111 is visible from the outside of the ink tank 100.

  The front wall 101 includes a base wall 101A extending in a generally vertical direction 7 from the lower wall 105, and an inclined wall 101B that is continuous with the base wall 101A at the upper end of the base wall 101A and is inclined with respect to the vertical direction 7 and the front-rear direction 8. It consists of The inclined wall 101B is formed with an inlet 112 that penetrates the inclined wall 101B in the thickness direction. The inclined wall 101B is inclined rearward (that is, the ink chamber 111 side) with respect to the base wall 101A. More specifically, it is desirable that the outer surface of the inclined wall 101B facing the outside of the ink tank 100 is monotonously inclined upward toward the ink chamber 111 between the inlet 112 and the base wall 101A.

  Note that “inclined monotonously toward the ink chamber 111 toward the upper side” means, for example, a relationship in which the connection position of two continuous surfaces in the up-down direction 7 is positioned higher as the distance from the base wall 101A increases. Of the two surfaces that are continuous in the vertical direction 7 (in this embodiment, the outer surfaces of the base wall 101A and the inclined wall 101B), the upper surface (in this embodiment, the outer surface of the inclined wall 101B) is the lower surface. In the present embodiment, the relationship is inclined toward the ink chamber 111 from the outer surface of the base wall 101A. And when the outer surface of the inclined wall 101B between the injection port 112 and the base wall 101A is composed of a plurality of surfaces having different inclination angles, the above relationship is obtained in all combinations of two surfaces that are continuous in the vertical direction 7. (That is, the upper surface is closer to the horizontal surface).

  When the above relationship is established, the outer surface of the inclined wall 101B extending from the injection port 112 to the base wall 101A is not formed with a structure that can spill ink from the injection port 112 and propagate along the outer surface of the inclined wall 101B. In addition, the structure which can block an ink is a convex part, a rib, a recessed part, a groove | channel, a hollow, etc., for example. Further, the outer surface of the inclined wall 101B between the injection port 112 and the base wall 101A is not limited to a flat surface, and may be a curved surface. More specifically, the outer wall of the inclined wall 101B may be a curved surface that bulges outward. In this case, the tangent at the upper position only needs to be inclined toward the ink chamber 111 with respect to the tangent at the lower position.

[Ink chamber 111]
Inside the ink tank 100, as shown in FIG. 5, a plurality of partition walls 107, 108, and 109 are provided to partition the internal space. Each of the partition walls 107, 108, and 109 extends in the up-down direction 7 and the front-rear direction 8, and is connected to the front wall 101, the upper wall 104, the lower wall 105, and the film 106. Further, the partition walls 107 to 109 are spaced apart in the left-right direction 9. As a result, the internal space of the ink tank 100 is partitioned into four ink chambers 111B, 111M, 111C, and 111Y adjacent in the left-right direction 9. The ink chamber 111 is an example of a liquid storage chamber that stores ink discharged from the nozzles 40.

  The ink chamber 111 </ b> B is a space defined by the front wall 101, the right wall 102, the upper wall 104, the lower wall 105, the film 106, and the partition wall 107. The ink chamber 111M is a space defined by the front wall 101, the upper wall 104, the lower wall 105, the film 106, and the partition walls 107 and 108. The ink chamber 111 </ b> C is a space defined by the front wall 101, the upper wall 104, the lower wall 105, the film 106, and the partition walls 108 and 109. The ink chamber 111 </ b> Y is a space defined by the front wall 101, the left wall 103, the upper wall 104, the lower wall 105, the film 106, and the partition wall 109.

  Hereinafter, the ink chambers 111B, 111M, 111C, and 111Y may be collectively referred to as “ink chamber 111”. Further, four constituent elements corresponding to each ink chamber 111 are given different reference numbers only in the last alphabet (B, M, C, Y). Sometimes abbreviated.

  Each ink chamber 111 stores different colors of ink. Specifically, black ink is stored in the ink chamber 111B, cyan ink is stored in the ink chamber 111C, magenta ink is stored in the ink chamber 111M, and yellow ink is stored in the ink chamber 111Y. Each color ink is an example of a liquid. However, the number of ink chambers 111 and the ink color are not limited to the above example. The ink chamber 111 is arranged along the left-right direction 9. Of the four ink chambers 111B, 111M, 111C, and 111Y, the ink chamber 111B is disposed on the rightmost side, and the ink chamber 111Y is disposed on the leftmost side. Further, the ink chamber 111B has a larger volume than the other ink chambers 111M, 111C, and 111Y.

[Inlet 112]
The inclined wall 101B of the ink tank 100 is provided with inlets 112B, 112M, 112C, and 112Y for injecting ink into the ink chambers 111. The inlet 112 penetrates the inclined wall 101B in the thickness direction, and connects the corresponding ink chamber 111 to the outside of the ink tank 100. The inclined wall 101 </ b> B has an inner surface facing the ink chamber 111 and an outer surface facing the outside of the ink tank 100. The inclined wall 101B is inclined so that the outer surface is located above the inner surface. Accordingly, the inlet 112 directly connects the ink chamber 111 and the outside of the ink tank 100. That is, there is no flow path between the injection port 112 and the ink chamber 111 that has a smaller sectional area than the injection port and is bent. Further, the inlet 112 may be provided in the upper wall 104 instead of the inclined wall 101B.

  The inclined wall 101B and the inlet 112 provided in the inclined wall 101B are exposed to the outside of the multifunction machine 10 by positioning the cover 70 at the exposed position, as shown in FIG. The injection port 112 is provided in the inclined wall 101 </ b> B in front of the opening 22. In the present embodiment, the posture (injection posture) of the ink tank 100 when ink is injected into the ink chamber 111 through the injection port 112 coincides with the posture of the ink tank 100 when the multifunction machine 10 is in the use posture. That is, ink is injected into the ink chamber 111 through the injection port 112 when the multifunction machine 10 is in the use posture. Although the injection port 112 in this embodiment is circular, the shape of the injection port 112 is not limited to this, and may be elliptical, polygonal, or the like.

  The ink tank 100 includes caps 113B, 113M, 113C, and 113Y that can be attached to and detached from the inlet 112. As shown in FIG. 1A, the cap 113 attached to the injection port 112 is in close contact with the periphery of the injection port 112 to close the injection port 112. On the other hand, as shown in FIG. 1B, the cap 113 removed from the injection port 112 opens the injection port 112. The cap 113 is attached to and detached from the inlet 112 with the cover 70 positioned at the exposed position. In addition, by removing the cap 113 from the injection port 112, ink can be injected into the ink chamber 111.

[Ink outflow path 114]
As shown in FIGS. 6 to 9, ink outflow paths 114 </ b> B, 114 </ b> M, 114 </ b> C, 114 </ b> Y (an example of a liquid outflow path) are connected to each ink chamber 111. The ink outflow passage 114 is a passage through which ink stored in the corresponding ink chamber 111 flows out of the ink tank 100.

The air communication path 126 allows air to flow in and out between the ink chamber 111 and the outside of the ink tank 100.

[Slit 72]
As shown in FIG. 1A, the cover 70 is provided with slits 72B, 72M, 72C, and 72Y. The slit 72 has a vertically long rectangular shape that continues in the vertical direction 7. The slit 72 functions as a transmission part that makes the front wall 101 of the ink tank 100 visible from the outside of the multifunction device 10 in a state where the cover 70 is located at the covering position. On the other hand, an area of the cover 70 different from the slit 72 functions as a non-transmissive portion that makes the front wall 101 of the ink tank 100 invisible from the outside of the multifunction machine 10 in a state where the cover 70 is located at the covering position. .

  As shown in FIGS. 10 and 11, the slit 72 </ b> B includes an opening 73 </ b> B that penetrates the cover 70 in the thickness direction and a film 74 </ b> B (an example of a transmissive member and a thin film) that closes the opening 73 </ b> B. The film 74B is made of a light transmissive material. The film 74 </ b> B in this embodiment is attached to the periphery of the opening 73 </ b> B on the outer surface of the cover 70 (that is, the surface opposite to the inner surface of the cover 70 facing the front wall 101). As a result, the front wall 101 and the film 74B are separated from each other in the front-rear direction 8. The configuration of the slits 72M, 72C, and 72Y is common to the slit 72B. However, the specific configuration of the slit 72 is not limited to this.

  Each slit 72 passes through the lower end of the corresponding inlet 112 (in this embodiment, the center of the opening of the circular inlet 112) in a state where the cover 70 is located at the covering position as shown in FIG. In addition, the first imaginary line 151B, 151M, 151C, 151Y (the one-dot chain line in FIG. 12) extending in the up-down direction 7 along the outer surface of the front wall 101 is one of the left and right directions 9 (right in this embodiment). It is provided at a shifted position. In other words, the area of the front wall 101 including the first imaginary line 151 faces the non-transmissive portion of the cover 70 at the covering position. Each slit 72 passes right and left second imaginary lines 152B, 152M, 152C, and 152Y (one-dot chain line in FIG. 12) that passes through the right end of the corresponding inlet 112 and extends in the vertical direction 7 along the outer surface of the front wall 101. It is provided at a position across the direction 9.

[Ink container 75]
Further, as shown in FIGS. 10 and 11, an ink storage portion 75 (an example of a liquid storage portion) is provided on the inner surface of the cover 70 (that is, the upper surface of the cover 70 at the exposed position). As shown in FIG. 10, the ink containing portion 75 is provided in the non-transmissive portion of the cover 70. Further, as shown in FIG. 11, the ink containing portion 75 is provided on the rear side (that is, the side close to the ink chamber 111) from the rotation shaft 71 of the cover 70 in the exposed position. In addition, the ink containing portion 75 is disposed below the injection port 112 in the vertical direction 7 and between the front wall 101 and the cover 70 in the front-rear direction 8 with the cover 70 positioned at the exposed position. Further, the ink containing portion 75 is provided at a position through which each first virtual line 151 passes in a state where the cover 70 is located at the exposed position.

  The ink containing portion 75 is partitioned by a pair of ribs 75A and 75B that project from the inner surface of the cover 70 and extend in the left-right direction 9. In addition, the ink containing portion 75 is filled with an ink absorbing member 76 (liquid absorbing member). In a state where the cover 70 is located at the exposed position, the upper surface of the ink absorbing member 76 is exposed. The ink absorbing member 76 is formed of a porous material such as foamed polyurethane, for example.

[Operational effects of this embodiment]
In the MFP 10 configured as described above, for example, as illustrated in FIG. 12, when ink is injected into the ink chamber 111 through the injection port 112, a case where a small amount of ink spills out of the ink tank 100 from the injection port 112 is considered. . When a small amount of ink spills from the inlet 112, the ink leaks out of the ink tank 100 from the lower end of the inlet 112 communicating with the outside of the ink tank 100, and along the first imaginary line 151. It runs down the outer surface of the front wall 101. That is, the outer surface of the front wall 101 including the first virtual line 151 is contaminated with ink.

  Therefore, according to the above-described embodiment, the region including the first virtual line 151 on the outer surface of the front wall 101 is covered with the non-transmissive portion of the cover 70 at the covering position. As a result, the contamination of the outer surface of the front wall 101 due to the ink can be made difficult to see from the outside of the multifunction machine 10. On the other hand, the slit 72 of the cover 70 at the covering position is opposed to a position shifted in the left-right direction with respect to the first virtual line 151 on the outer surface of the front wall 101. Thereby, it is possible to suppress a decrease in visibility inside the ink chamber 11 from the outside of the multifunction device 10.

  Moreover, according to said embodiment, the slit 72 is made to face the area | region which straddles the 2nd virtual line 152 among the outer surfaces of the front wall 101. FIG. Thereby, for example, even if ink spills from the injection port 112 at a position shifted in the left-right direction 9 from the first imaginary line 151, it is possible to prevent the inside of the ink chamber 111 from being completely invisible from the outside of the multifunction machine 10. .

  In particular, when the length of each ink chamber 111 in the left-right direction 9 is shortened for compactness, the distance between the partition walls 107 to 109 and the first virtual line 151 is shortened, and the space of the slit 72 is secured. It becomes difficult. Therefore, according to the above embodiment, the slit 72 can be provided at a position shifted from the first imaginary line 151 while facing the slit 72 in a region straddling the second imaginary line 152 in the outer surface of the front wall 101. . As a result, it is possible to prevent the inside of the ink chamber 111 from being completely visually recognized while increasing the width of the slit 72 in the left-right direction 9 to improve the visibility. However, the position of the slit 72 is not limited to this, and for example, the slit 72 may face the region between the first virtual line 151 and the second virtual line 152 in the outer surface of the front wall 101.

  Further, since the slit 72 functioning as the transmission portion is formed in a vertically long rectangular shape that is continuous in the vertical direction 7, it is easy to grasp the remaining amount of ink in the ink chamber 111 from the outside of the multifunction machine 10. However, the shape of the transmission part is not limited to this, and for example, a plurality of transmission parts may be discretely arranged in the vertical direction 7. Moreover, since the film 74 which comprises a permeation | transmission part was spaced apart from the outer surface of the front wall 101, the fall of visibility by the film 74 being contaminated can be suppressed. As shown in FIG. 11, the contamination of the cover 70 can be further suppressed by separating the inner surface of the cover 70 at the covering position and the outer surface of the front wall 101.

  Further, the ink that has flowed down from the inlet 112 to the outer surface of the front wall 101 is absorbed by the ink absorbing member 76 of the ink containing portion 75. As a result, the ink can be prevented from leaking out of the multifunction device 10. Further, since the ink containing portion 75 is provided in the non-transmissive portion of the cover 70, the ink containing portion 75 and the ink absorbing member 76 are difficult to see from the outside of the multifunction machine 10 in a state where the cover 70 is located at the covering position. Note that the position of the ink storage portion 75 is not limited to the inner surface of the cover 70 as long as the ink that flows down the outer surface of the front wall 101 can be stored. For example, the ink storage unit 75 may be provided on the support surface 28 of the casing of the multi-function device 10, or provided on the outer surface of the base wall 101 </ b> A and at the position facing the non-transmissive portion of the cover 70 at the covering position. May be.

Further, the non-transmissive portion 162 is provided in the entire area of the front wall 101 below the injection port 112 in the vertical direction 7. Note that the second virtual lines 153B, 153M, 153C, and 153Y shown in FIG. 14 are virtual lines that pass through the left end of the corresponding inlet 112 and extend in the vertical direction 7 along the outer surface of the front wall 101.

  The transmission part 163 is provided on the outer surface of the front wall 101 at a position shifted to one of the left and right directions 9 with respect to the first virtual line 151.
