At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
A urine passage portion having a plurality of slits through which urine passes, and a urine passage portion that has a front-rear direction, a left-right direction, and a height direction, and an absorption that is provided below the urine passage portion and absorbs urine that has passed through the urine passage portion An animal restroom with a body installed thereon, wherein the slit is surrounded by a longitudinal rib along the front-rear direction and a lateral rib along the left-right direction In the lower surface of the urine passage portion, the height of the longitudinal rib is higher than the height of the lowest portion of the lateral rib provided on at least one of the front and rear sides in the front-rear direction. The toilet for animals is characterized by being expensive.

  According to such an animal toilet, since the height of the lowest part of the lateral rib is lower than the height of the longitudinal rib at the front or rear end in the front-rear direction of the urine passage part, the front-rear direction When brushing the brush, the brush is less likely to be caught by the lateral ribs. Thereby, at the beginning and the end of the application of the brush, the movement of the brush in the front-rear direction is less likely to be interfered, and the urine passage portion can be easily cleaned.

  In such an animal toilet, it is desirable that in the slit, the interval between the horizontal ribs adjacent in the front-rear direction is wider than the interval between the vertical ribs adjacent in the left-right direction.

  According to such an animal toilet, when the brush is moved in the front-rear direction by forming the slit in a vertically long shape along the front-rear direction, the brush can easily pass to the depth in the height direction of each slit. Easy to clean.

  In such an animal toilet, it is desirable that the height of the vertical rib is higher than the height of the lowest part of all the horizontal ribs of the urine passage.

  According to such an animal toilet, the vertical rib functions as a guide for moving the brush in the front-rear direction in all areas of the urine passage, and the movement of the brush in the front-rear direction interferes with the horizontal rib. This makes it easier to move the brush back and forth smoothly. Thereby, cleaning of a urine passage part can be performed more efficiently.

  In this animal toilet, a curved portion that is recessed in an arc shape is formed on the lower side of the horizontal rib, and the position of the apex of the curved portion is the lowest in the horizontal rib. It is desirable to be a part.

  According to such an animal toilet, urine does not stay along the curved surface portion (notch portion) and can easily move from the upper side to the lower side. Moreover, even if dirt adheres, if the cutout portion has a curved surface, the brush tip of the brush is easily reached as a whole, so that the dirt can be easily removed. This makes it easier to clean the urine passage.

  In such an animal toilet, the height of the curved surface portion formed on the horizontal rib provided on at least one of the front and back sides in the front-rear direction is the height of the front side rib. It is desirable that it is 1/3 or more.

  According to such an animal toilet, since a curved surface portion (notch) having a certain size or more is formed on the horizontal rib, the brush is moved in the front-rear direction while preventing dirt from collecting in the notch portion. It is possible to further reduce the interference caused by the lateral ribs.

  In such an animal toilet, it is desirable that a lower end portion of the vertical rib has a horizontal planar shape.

  According to such an animal toilet, since the protruding end portion of the vertical rib protruding in the height direction on the lower surface side of the urine passage portion is planar, the operation of moving the brush in the front-rear direction along the vertical rib interferes. It becomes hard to be done and becomes easy to perform cleaning.

  The toilet for animals has an upper container provided with the urine passage part, and the center position of the urine passage part is arranged on the rear side of the center position of the upper container in the front-rear direction. It is desirable that

  According to such an animal toilet, since the urine passage portion is disposed closer to the rear in the front-rear direction, the front portion of the upper container is less prone to urine and the like and is less likely to get dirty. Thereby, since it becomes possible to grasp the front part with little dirt at the time of cleaning, it can make it difficult to produce discomfort to the user.

  In such an animal toilet, a step portion which is a portion where a height difference is formed in the height direction is provided in a region on the front side in the front-rear direction of the upper container. It is desirable to have a front step part and a rear step part which is located on the rear side in the front-rear direction with respect to the front step part and has a larger inclination than the front step part.

  According to such an animal toilet, the user can stably apply the brush by grasping the step portion when performing the operation of applying the brush to the urine passage portion. In addition, since the front stepped portion formed on the front side of the stepped portion has a gentle inclination, the user can easily grasp the region of the front stepped portion and can hold the upper container firmly.

<Overall configuration>
An animal toilet 1 will be described as an example of an animal toilet according to the present embodiment. FIG. 1 is a schematic perspective view of an animal toilet 1. FIG. 2 is an exploded side view of the animal toilet 1. Further, in the following description, as shown in FIG. 1, “front-rear direction”, “left-right direction”, and “height direction” that are three directions orthogonal to each other are defined. The front-rear direction is a direction along the longitudinal direction of the animal toilet 1, and the side on which the animal doorway is provided is the front side. The left-right direction is a direction along the width direction of the animal toilet 1. The height direction is a direction along the vertical direction.

  The animal toilet 1 includes an upper container 10, a lower container 20, a tray 30, and a cover 40, and the animal toilet 1 in use as shown in FIG. 1 is formed by these four members. The four members can be freely disassembled and assembled as shown in FIG. Specifically, the lower container 20 is assembled under the upper container 10 in an overlapping manner. The lower container 20 accommodates a tray 30 on which an absorber (absorber 220 described later) that absorbs excreted urine and the like can be installed. A cover 40 is assembled above the upper container 10. Thus, since each member can be disassembled from each other, cleaning work and the like are facilitated.

The upper container 10, the lower container 20, the tray 30, and the cover 40 are each formed of a polyolefin-based thermoplastic resin such as polyethylene, polypropylene, and polyethylene terephthalate. However, the material which forms each member is not restricted to this, For example, metal plates, such as another resin, a stainless steel plate, and an aluminum plate, may be sufficient.

  FIG. 3 is a three-side view of the upper container 10. FIG. 4 is a diagram for explaining the AA cross section of FIG. 3. The upper container 10 is a substantially box-shaped member opened upward, and an animal such as a cat excretes on the upper surface side of the upper container 10 (that is, the inside of the box). The upper container 10 has a bottom part 11, an edge part 12, a step part 13, and an inclined part 14.

The bottom part 11 is provided with a urine passage part 100 through which urine excreted by an animal passes from the upper side to the lower side in the height direction. The urine passage 100 has a plurality of holes 101 penetrating in the height direction, and excreted urine passes through the holes 101 and moves from the upper side to the lower side of the upper container 10.

  When the animal toilet 1 is used, granular materials such as cat sand are installed on the upper surface of the urine passage 100, and animals such as cats excrete on the granular materials. In this embodiment, the excrement disposal material 210 is installed as a granular material as shown in FIG. The excrement disposal material 210 is a granular material having a porous structure, such as zeolite or silica gel, and has an effect of absorbing and deodorizing ammonia components by contacting with urine excreted by animals and moisture. Has the effect of removing. Moreover, since the granular excrement disposal material 210 is installed in the urine passage part 100, the animal can easily recognize that the part (the urine passage part 100) is a place where excretion should be performed. In addition, in order to suppress that each grain of the excrement disposal material 210 falls downward from the hole 101 of the urine passage portion 100 (bottom portion 11), the excrement disposal material 210 passes through the hole 101 while allowing the urine to pass therethrough. It is desirable that the shape and size are not allowed. In this embodiment, the hole 101 is a slit long in the front-rear direction as shown in FIG. Hereinafter, the hole 101 is also referred to as a slit 101.

  The edge portion 12 is a portion constituting the outer edge of the upper container 10 in the front-rear direction and the left-right direction, and includes a front edge portion 12f, a rear edge portion 12b, a right edge portion 12r, and a left edge portion 121. The edge portion 12 has a shape folded outward at the upper end portion of the upper container 10 and can be overlapped with an edge portion 22 of the lower container 20 described later in the height direction.

  The step portion 13 is a portion where a height difference is formed between the front edge portion 12f and the bottom portion 11, and is a front step portion 13a that is a front side region in the front-rear direction and a rear side region in the front-rear direction. And a rear step portion 13b. The front step 13a and the rear step 13b have different inclination angles. In the animal toilet 1, the front step 13a has a lower inclination than the rear step 13b. Thereby, a step as shown in FIG. 4 is formed between the front step portion 13a and the rear step portion 13b.

  The inclined portion 14 includes a rear inclined portion 14b, a right inclined portion 14r, and a left inclined portion 14l. The rear inclined part 14b is a part connecting the rear edge part 12b and the bottom part 11, the right inclined part 14r is a part connecting the right edge part 12r and the bottom part 11, and the left inclined part 14l is connected to the left edge part 12l. It is a part connecting the bottom part 11. Each portion forms an inclined portion between the edge portion 12 and the bottom portion 11, whereby the upper container 10 is formed in a substantially box shape as shown in FIGS. 3 and 4.

  FIG. 5 is a three-side view of the lower container 20. The lower container 20 is a substantially box-shaped member having an upper opening, and is assembled under the upper container 10 as shown in FIGS. 1 and 2 when the animal toilet 1 is used. The lower container 20 includes a bottom portion 21, an edge portion 22, a side wall portion 23, and a tray accommodating portion 25. The bottom portion 21 is a portion constituting the bottom surface of the lower container 20. The edge 22 is a portion constituting an outer edge in the front-rear direction and the left-right direction in the upper part of the lower container 20, and has a front edge 22f, a rear edge 22b, a right edge 22r, and a left edge 22l. . When the lower container 20 is assembled with the upper container 10, the edge 12 of the upper container 10 and the edge 22 of the lower container 20 are overlapped. The side wall portion 23 is a wall member that stands upward from the end edge portion of the bottom portion 21, and includes a front side wall portion 23f, a rear side wall portion 23b, a right side wall portion 23r, and a left side wall portion 23l.

  The tray accommodating portion 25 is a portion that accommodates the tray 30. As shown in FIG. 5, an opening 25 f is provided below the front side edge 22 f, and the tray 30 is moved in the front-rear direction from the opening 25 f along the tray accommodating portion 25 represented by the broken line portion of FIG. 5. The tray 30 can be accommodated inside the lower container 20 by sliding and moving backward.

  FIG. 6 is a three-side view of the tray 30. The tray 30 is a flat box-like container having a shallow bottom on which an absorber that absorbs urine and the like is installed. The tray 30 includes a side wall part 31, an absorber installation part 32, and a handle part 33. The side wall portion 31 is a wall surface that surrounds the outer periphery of the tray 30. In the present embodiment, the tray 30 is formed in a rectangular shape that is symmetrical in the front-rear direction. And the absorber installation part 32 which installs an absorber in the inner area | region enclosed by the side wall part 31 is formed.

  FIG. 6 shows a state where the absorber 220 (represented by the hatched portion in the figure) is installed in the absorber installation section 32. The absorber 220 is a liquid-absorbing sheet member that absorbs urine excreted by an animal such as a cat, and is formed of a liquid-absorbing material such as pulp fiber or a superabsorbent polymer. Further, deodorant microcapsules and antibacterial agents may be included in the absorbent body 220 to contain the odor of absorbed urine and prevent germs from growing. In FIG. 6, the absorbent body 220 is represented as a rectangular sheet member. However, as long as the absorbent body 220 can be held by the absorbent body installation portion 32, the shape of the absorbent body 220 is not limited.

  The handle portion 33 is a part formed at both ends in the front-rear direction of the tray 30. When the tray 30 is accommodated in the lower container 20 or pulled out from the lower container 20, the handle portion 33 is By grasping and operating, the tray 30 can be slid in the front-rear direction. As described above, since the tray 30 of the present embodiment has a symmetrical shape in the front-rear direction, it can be accommodated in the lower container 20 by exchanging the front-rear direction.

  The cover 40 has an entrance / exit opening 41, a side wall 42, and an edge 43, and is disposed above the upper container 10 and the lower container 20 (see FIG. 1). The entrance / exit opening 41 is a portion that is wide open on the front side in the front-rear direction, and animals can enter and exit the animal toilet 1 through the entrance / exit opening 41. That is, the entrance / exit opening 41 corresponds to an entrance / exit of the animal toilet 1. The side wall portion 42 is formed around the entrance / exit opening 41 and includes a left side wall portion 42 f and a right side wall portion 42 r that cover both sides of the cover 40 in the left-right direction, and a rear side wall portion 42 b that covers the rear side in the front-rear direction of the cover 40. By providing the side wall portion 42, it is possible to prevent the granular absorbent body 220 and excrement from spilling or scattering outside the animal toilet 1 (upper container 10).

  Moreover, in this embodiment, as FIG.1 and FIG.2 shows, it forms so that the height of the left side wall part 42f and the right side wall part 42r may become low toward the front side. Thus, while suppressing the scattering of the absorber 220 on the rear side, a wide field of view of the animal is ensured on the front side, so that it is easy to check the outside from the toilet. By ensuring sufficient visibility even during excretion, the animal toilet 1 can be used with peace of mind. The edge 43 is a portion constituting an outer edge below the cover 40, and includes a front edge 43f, a rear edge 43b, a left edge 43l, and a right edge 43r. Since the edge 43 is engaged with the edge 22 of the lower container 20, the cover 40 can be assembled and fixed to the animal toilet 1.

  When animals such as cats excrete, they enter the animal toilet 1 through the entrance / exit opening 41 and enter the portion of the urine passage 100 where the granular excrement disposal material 210 is disposed on the upper surface of the upper container 10. Excrete urine. The excreted urine passes through the plurality of slits 101 of the urine passage part 100 while being in contact with the excrement disposal material 210 and falls downward. Then, it is absorbed by the absorbent body 220 disposed below the urine passage 100 and stored in the tray 30. The user can cleanly use the animal toilet 1 by periodically replacing the absorbent body 220 that has absorbed urine.

<About cleaning of urine passage 100>
When the animal toilet 1 is used, it is necessary to periodically clean it. In particular, the urine passage portion 100 provided in the bottom portion 11 of the upper container 10 is a portion that comes into contact with urine each time excretion is performed by an animal, and thus is one of the most easily contaminated portions of the animal toilet 1. . In the urine passage unit 100, urine moves from the upper surface side to the lower surface side and drops downward. At that time, urine that does not drop downward and remains on the lower surface side tends to cause contamination. Therefore, it is desirable to sufficiently clean the lower surface side of the urine passage 100 when cleaning. Specifically, it is desirable to remove the dirt adhering to the slit 101 by turning the upper container 10 upside down and brushing the entire lower surface of the urine passage 100.

  In the animal toilet 1 of the present embodiment, the shape of the lower surface side of the urine passage portion 100 is different from that of a conventional animal toilet so that the brush can be easily applied and can be efficiently cleaned. Hereinafter, the structure of the urine passage part 100 will be described.

<Structure of urine passage 100>
FIG. 7 is an enlarged view of the region D in FIG. 3, and is a partially enlarged view of the urine passage part 100. As described above, the urine passage 100 is provided at the bottom 11 of the upper container 10 and has a plurality of slits 101 (holes 101) penetrating in the height direction. Each slit 101 is formed by surrounding the outer periphery with vertical ribs 111 arranged in the front-rear direction and horizontal ribs 115 arranged in the left-right direction, and arranged side by side in the front-rear direction and the left-right direction. . In FIG. 7, the vertical rib 111 is indicated by hatching.
As shown in FIG. 7, the slit 101 is a vertically long hole extending in the front-rear direction. That is, the interval between the two adjacent horizontal ribs 115 (the distance in the front-rear direction) is longer than the interval between the two adjacent vertical ribs 111 (the distance in the left-right direction). Further, as shown in FIGS. 1 and 3, the upper container 10 itself has a vertically long structure that is long in the front-rear direction, and it is easy to apply a brush along the longitudinal direction.

  Of the plurality of horizontal ribs 115 of the urine passage part 100, the one disposed on the most front side in the front-rear direction is referred to as a front horizontal rib 115f (see FIG. 7). Similarly, among the plurality of horizontal ribs 115, the one disposed on the most front side in the front-rear direction is referred to as a rear side rib 115b (not shown). The rear lateral rib 115b has substantially the same structure as the front lateral rib 115f. Details of the rib shape will be described below.

  FIG. 8A is a diagram illustrating the BB cross section of FIG. 7. That is, FIG. 8A is a diagram illustrating the shapes of the vertical rib 111 and the front horizontal rib 115f. However, when the BB cross section is viewed from the front side in the front-rear direction, the boundary portion between the vertical rib 111 and the horizontal rib 115h is not visible, so the shape of the vertical rib 111 is represented by a broken line. FIG. 8B is a diagram illustrating the CC cross section of FIG. 7. That is, FIG. 8B is a diagram illustrating the shapes of the vertical ribs 111 and the horizontal ribs 115. FIG. 9 is a schematic perspective view of the urine passage 100 when viewed from the lower surface side.

  As shown in FIG. 8A, the vertical rib 111 has a height of 111h1 in the height direction from the lower surface of the bottom portion 11 (upper container 10), and the width in the left-right direction gradually decreases from the top to the bottom. Shaped member. In FIG. 8A, a space formed between two vertical ribs 111 adjacent in the left-right direction is an interval in the short direction of the slit 101. Moreover, the vertical rib 111 has the vertical rib plane part 112 in a lower end part. The vertical rib flat surface portion 112 is a portion in which the end of the vertical rib 111 is formed in a horizontal flat shape, and the height 111 h 1 of the vertical rib 111 depends on the distance between the lower surface of the bottom portion 11 and the vertical rib flat surface portion 112. expressed. The urine excreted on the upper surface side of the urine passage part 111 moves downward while flowing on the surface of the vertical rib 111, leaves the vertical rib 111 at the vertical rib flat part 112, and falls downward.

  On the other hand, the front lateral rib 115f is a plate-like member having a height of 115fh1 in the height direction from the lower surface of the bottom portion 11 of the upper container 10 and extending in the left-right direction, and spans between the vertical ribs 111 arranged in the left-right direction. Arranged to pass. The height 115fh1 of the front lateral rib 115f and the height 111h1 of the vertical rib 111 are the same height. That is, the lower ends of the front lateral rib 115f and the longitudinal rib 111 are both on the same plane (see FIGS. 8A and 9). And the front side horizontal rib 115f has the horizontal rib plane part 116 in which the lower end part was formed in the horizontal plane shape similarly to the vertical rib 111. In FIG. 9, for the sake of explanation, the horizontal rib plane portion 116 is drawn so as to largely protrude in the left-right direction from the vertical rib 111, but actually, the width of the horizontal rib plane portion 116 in the left-right direction is about 2 mm. The protruding part in the left-right direction is not large.

  In addition, a curved surface portion 117 that is a cutout portion that is recessed in an arc shape or a parabolic shape is formed on the lower end portion of the front lateral rib 115f at an intermediate position between two longitudinal ribs 111 adjacent in the left-right direction. Yes. A portion corresponding to the apex of the parabola of the curved surface portion 117 is defined as a curved bottom portion 117b, and the curved bottom portion 117b is a portion where the height of the front lateral rib 115f is the lowest. That is, in the front lateral rib 115f, the distance between the lower surface of the bottom portion 11 and the curved bottom portion 117b is the shortest, and the height of the portion is represented by 115fh1b.

  Next, in FIG. 8B, the vertical rib 111 has a height of 111h2 in the height direction from the position of the upper surface of the bottom portion 11 (the upper surface of the urine passage portion 100). Except for the height, it is substantially the same as the vertical rib 111 described in FIG. 8A. Further, the lateral rib 115 has a height of 115 h 2 in the height direction from the position of the upper surface of the bottom portion 11 (the upper surface of the urine passage portion 100). A curved surface portion 117 is formed at the lower end portion of the lateral rib 115 in the same manner as the front lateral rib 115h, and the curved bottom portion 117b is a portion where the height of the lateral rib 115 is the lowest. The height of the portion (the distance between the lower surface of the bottom portion 11 and the curved bottom portion 117b) is represented by 115h2b. The configuration other than the height of the lateral rib 115 is substantially the same as that of the front lateral rib 115h described with reference to FIG. 8A.

  As shown in FIG. 8A, in the urine passage portion 100 of the present embodiment, the curved surface where the position of the flat surface portion 112 which is the lower end portion of the vertical rib 111 is the lowest portion in the height direction of the front lateral rib 115f. It is lower than the position of the bottom 117b. In other words, the height 111h1 of the vertical rib 111 is higher than the height 115fh1b of the lowest portion in the height direction of the front lateral rib 115f (115fh1b <111h1). Similarly, as shown in FIG. 8B, the position of the flat surface portion 112 of the vertical rib 111 is lower than the position of the curved bottom portion 117 b of the horizontal rib 115. In other words, the height 111h2 of the vertical rib 111 is higher than the height 115fh2b of the lowest portion in the height direction of the horizontal rib 115 (115fh2b <111h2). That is, in the entire region on the lower surface side of the urine passage portion 100, the height of the vertical rib 111 is formed higher than the height of the lowest portion of the horizontal rib 115, the front side rib 115f, and the rear side rib 115b. Has been.

  With such a configuration, it becomes easy to apply a brush along the front-rear direction on the lower surface side of the urine passage 100 when cleaning. If an attempt is made to move the brush along the left-right direction, the brush is easily caught by the vertically formed vertical rib 111, and the movement of the brush is easily regulated (see FIG. 9). On the other hand, when the brush is moved along the front-rear direction, the height of the horizontal rib 115 is lower at the curved bottom portion 117b, so that the brush is less likely to be caught than the vertical rib 111, and the movement of the brush is less likely to be regulated. Further, since the vertical rib 111 functions as a guide for moving the brush and supports the movement of the brush in the front-rear direction, the brush can be moved smoothly.

  In particular, in the present embodiment, the height of the lowest part of the front lateral rib 115f formed at the front end portion in the front-rear direction of the urine passage portion 100 and the rear lateral rib 115b formed at the rear end portion is high. By being formed lower than the vertical rib 111, the brush movement in the front-rear direction is less likely to be interfered at the beginning and end of brush application. Thereby, it becomes easy to perform the operation | movement of brushing more stably, and it can clean efficiently.

  Further, as shown in FIG. 7, since the slit 101 is formed in a vertically long shape along the front-rear direction, when the brush is moved in the front-rear direction, the brush is located at the back of each slit 101 in the height direction. It is easy to pass through and easy to clean. Assuming that the slit 101 is formed in a horizontally long shape (long in the left-right direction), when the brush is moved in the front-rear direction, it is difficult for the hair of the brush to enter the back of the slit 101, and the dirt is sufficiently removed. It becomes difficult. However, in this embodiment, the interval between the horizontal ribs 115 adjacent in the front-rear direction is wider than the interval between the vertical ribs 111 adjacent in the left-right direction. Cleaning can be performed.

  In this embodiment, as shown in FIGS. 8A and 8B, the horizontal rib plane portion 116 protrudes in the left-right direction. However, as described above, the width of the horizontal rib plane portion 116 is about 2 mm. Actually, the area of the portion protruding in the left-right direction is small, and does not significantly interfere with the back-and-forth movement of the brush.

  Subsequently, attention is focused on the shape of the lateral rib 115 (including 115f and 115b). As described above, the lateral rib 115 is provided with a notch for reducing the height of the rib. In the present embodiment, as shown in FIG. 8, the curved surface portion 117 is formed as the notched portion of the lateral rib 115, but the notched portion is formed in an arc shape like the curved surface portion 117. This makes it possible to efficiently remove dirt during cleaning.

  When the animal toilet 1 is used, urine excreted by the animal flows from the upper side to the lower side through the surface of the horizontal rib 115 (and the vertical rib 111). Then, after reaching the horizontal rib plane portion 116 which is the lower end portion of the horizontal rib 115, the horizontal rib 115 is separated from the horizontal rib plane portion 116 and falls downward. At this time, if the shape of the notch portion of the lateral rib 115 is formed in a rectangular shape, urine tends to stay in the corner portion of the rectangular shape. Further, if the notch portion does not reach the lower end portion of the horizontal rib 115 and merges with the vertical rib 111 on the way, a step or a corner is generated in the merge portion, and urine tends to stay in the portion. When such a “corner” or the like is formed, urine is difficult to move downward and is likely to cause contamination. On the other hand, if it is an arc-shaped notch that reaches the lower end of the horizontal rib such as the curved surface portion 117, it is easy to smoothly move to the horizontal rib flat surface portion 116 at the lower end without retaining urine. It is difficult for urine to adhere to the surface of the lateral rib 115. Further, even if dirt is attached to the curved surface portion 117, the above-mentioned “corner” is not formed, so that the brush tip easily reaches the dirty portion. That is, since it becomes easy to apply a brush over the whole surface of the curved surface part 117, it becomes easy to remove dirt.

  In the present embodiment, by making the curved surface portion 117 as large as possible, the curved surface portion 117 can be brushed more easily. Specifically, on the most front side in the front-rear direction of the urine passage part 100, the height 117h of the curved surface part 117 formed on the front side rib 115f is 1/3 or more of the total height 115fh1 of the front side rib 115f. Thus, a curved surface portion 117 is formed. Here, the height 117h of the curved surface portion 117 is the difference between the height 115fh1 of the highest portion of the lateral rib 115f and the height 115fh1b of the lowest portion (that is, the distance between the flat portion 116 and the curved bottom portion 117b). (See FIG. 8A). By defining the size of the cutout portion (curved surface portion 117) in the lateral rib 115f in this way, it is difficult for dirt to accumulate in the cutout portion, and interference when the brush is moved in the front-rear direction is reduced. Can do. The same applies to the rearmost lateral rib 115b on the rearmost side in the front-rear direction of the urine passage 100.

  Moreover, about the vertical rib 111, it has the structure which is easy to clean by having the plane part 112 in a lower end part. That is, the projecting end portion of the vertical rib 111 protruding in the height direction on the lower surface side of the urine passage portion 100 is formed in a planar shape and interferes with the operation when the brush is moved in the front-rear direction along the vertical rib 111. Because there is little, it becomes easy to perform cleaning.

<About the shape of the upper container 10>
Although the structure of the urine passage 100 has been described, in the animal toilet 1, the upper container 10 itself is configured to easily clean the urine passage 100.

  In FIG. 3, CLa represents the center position in the front-rear direction of the upper container 10, and CLb represents the center position in the front-rear direction of the urine passage part 100. Comparing the center position CLa of the upper container 10 and the center position CLb of the urine passage 100, it can be seen that CLb is located on the rear side of CLa. This indicates that the urine passage portion 100 is disposed on the rear side in the front-rear direction in the upper container 10. Therefore, the upper container 10 can secure a wide space in the front side region in the front-rear direction, and the step portion 13 is formed in the front side region.

  When performing the operation of applying a brush to the urine passage portion 100, the user can apply the brush stably by grasping the step portion 13. Furthermore, since the front step portion 13a formed on the front side of the step portion 13 has a gentle inclination, the region can be easily grasped and the upper container 10 can be firmly held. As a result, the user can naturally perform an operation of holding the front portion of the upper container 10 with one hand and brushing the urine passage portion 100 with the other hand during cleaning.

  Moreover, since the urine passage part 100 is disposed closer to the rear in the front-rear direction, the stepped part 13 that is the front part of the upper container 10 is less likely to get urine or the like and is less likely to get dirty. That is, at the time of cleaning, a portion with less dirt (here, the step portion 13) can be grasped, so that it is difficult for the user to feel uncomfortable.
