[0001] The present invention relates to an animal toilet.

Background Art

[0002] As a conventional animal toilet, for example, there is one described in Patent Document 1. The animal toilet described in this document includes a main body ( tray ) for receiving excreted urine and a partition ( sieve ) for partitioning the internal space of the main body into an upper space and a lower space. The partition has a plurality of through - holes for allowing urine to pass through. A plurality of granular materials having low water absorption are laid in the upper space ( above the partition ). A water - absorbent sheet for absorbing urine is disposed in the lower space. The urine excreted into the main body passes through the gaps between the granular materials and then moves from the upper space to the lower space through the through - holes of the partition. The urine that has moved to the lower space accumulates in the lower space in a state of being absorbed by the water - absorbent sheet.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above - mentioned animal toilet, the odor generated from the urine accumulated in the lower space may leak into the upper space through the through - holes. This causes a bad smell to linger around the animal toilet. In order to suppress such odor leakage, it is conceivable to increase the arrangement pitch of the through - holes. However, if the arrangement pitch of the through - holes is increased, the smooth movement of urine from the upper space to the lower space will be hindered.

[0005] The present invention has been made in view of the above problems, and aims to provide an animal toilet that is suitable for suppressing the leakage of odor from the lower space to the upper space without hindering the smooth movement of urine from the upper space to the lower space. [Means for solving the problem]

[0006] The animal toilet according to the present invention comprises a main body that receives excreted urine, and a partition that divides the internal space of the main body into an upper space and a lower space, having a plurality of through holes through which the urine passes, wherein the plurality of through holes include a plurality of first through holes and a plurality of second through holes located outside the plurality of first through holes, and the arrangement pitch of the second through holes is larger than the arrangement pitch of the first through holes.

[0007] In this animal toilet, first and second through-holes are provided in the partition. The second through-holes are located further out than the first through-holes. The arrangement pitch of the second through-holes is larger than that of the first through-holes. By making the arrangement pitch of the second through-holes, which are located relatively further out, larger, odors generated from urine accumulated in the lower space are less likely to leak into the upper space. On the other hand, by making the arrangement pitch of the first through-holes, which are located relatively further inward, smaller, urine can move more smoothly from the upper space to the lower space. [Effects of the Invention]

[0008] According to the present invention, an animal toilet suitable for suppressing the leakage of odor from the lower space to the upper space is realized without hindering the smooth movement of urine from the upper space to the lower space. [Brief explanation of the drawing]

[Figure 3] This is a front view showing the main body 10. [Figure 4] This is a plan view showing the main body 10. [Figure 5] This is a plan view showing the partition section 20. [Figure 6] This is a perspective view showing the drawer section 50. [Figure 7] This is a plan view showing a modified partition 20. [Figure 8] This is an end view illustrating a modified example of the main body 10. [Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described in detail below with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted.

[0011] Figure 1 is an end view showing one embodiment of an animal toilet according to the present invention. The animal toilet 1 comprises a main body 10, a partition 20, a plurality of granular materials 30, an absorbent sheet 40, and a drawer 50. The animal toilet 1 is, for example, a cat toilet. The main body 10 consists of a single box-shaped container and has a bottom surface 10a and side surfaces 10b. The main body 10 receives the excreted urine. The external shape of the main body 10 is substantially a rectangular parallelepiped. As the material of the main body 10, for example, plastic can be used. Examples of plastics include polypropylene or polyethylene.

[0012] Figures 2 and 3 are an end view and a front view, respectively, of the main body 10. An opening 12 for inserting and removing the drawer 50 is formed in the side portion 10b of the main body 10. The opening 12 is located near the bottom portion 10a and has a horizontally elongated rectangular shape. The length of the opening 12 in the horizontal direction (left-right direction in Figure 3) is approximately equal to the width (internal dimension) of the main body 10, for example, 20 cm or more and 40 cm or less. The length of the opening 12 in the vertical direction (up-down direction in Figure 3) is for example, 2 cm or more and 5 cm or less.

[0013] Figure 4 is a plan view showing the main body 10. The main body 10 has a support portion 14. The support portion 14 protrudes inward from the side portion 10b of the main body 10. The support portion 14 supports the partition portion 20 from below. In plan view, the support portion 14 is provided along the entire inner circumference of the side portion 10b. That is, the support portion 14 consists of a protrusion provided in an annular shape along the inner circumference of the side portion 10b. In plan view, the inner circumference of the side portion 10b is approximately rectangular. Here, "approximately rectangular" does not mean a rectangle, but also includes shapes close to a rectangle, such as a rounded rectangle. The protruding length of the support portion 14 (the length in the direction perpendicular to the inner surface of the side portion 10b on which the support portion 14 is provided) is, for example, 5 mm or more and 15 mm or less. The support portion 14 may be molded integrally with the side portion 10b, or it may be molded separately from the side portion 10b and then attached to the side portion 10b.

[0014] Figure 5 is a plan view showing the partition 20. The partition 20 is placed on the support 14. The partition 20 is not fixed to the main body 10. The partition 20 is detachable from the main body 10. The partition 20 can be installed inside the main body 10 with its entire perimeter spaced apart from the side portion 10b. The partition 20 is made of a plate-like material and is flat. Therefore, the entire upper surface of the partition 20 is in the same plane, as is the entire lower surface of the partition 20. In plan view, the partition 20 is roughly rectangular in shape. The partition 20 is arranged parallel to the bottom surface 10a. The partition 20 is also positioned spaced apart from both the upper end of the main body 10 (side portion 10b) and the absorbent sheet 40. As a result, the partition 20 divides the internal space of the main body 10 into an upper space S1 and a lower space S2. The upper space S1 is located above the partition 20 and is the space where multiple granular materials 30 are laid. The lower space S2 is located below the partition 20 and is the space where urine accumulates. For example, plastic can be used as the material for the partition 20.

[0015] The partition 20 has multiple through-holes 22 through which urine passes. In the following description, unless otherwise specified, "multiple through-holes 22" refers to all the through-holes 22 provided in the partition 20. Each through-hole 22 allows urine to pass through but does not allow the granular material 30 to pass through. The multiple through-holes 22 are arranged two-dimensionally in the partition 20. The planar shape of each through-hole 22 is circular. The diameter of each through-hole 22 is, for example, 2 mm or more and 10 mm or less.

[0016] The multiple through holes 22 include multiple through holes 22a (first through holes) and multiple through holes 22b (second through holes). In this embodiment, the multiple through holes 22 consist only of through holes 22a and through holes 22b. The multiple through holes 22 are located at the same height. That is, the distance from each through hole 22 to the bottom surface 10a is constant. Therefore, the through holes 22b are located at the same height as the through holes 22a. However, the through holes 22b are located outside the through holes 22a. That is, in a plan view, the shortest distance from the through holes 22b to the outer circumference of the partition 20 is smaller than the shortest distance from the through holes 22a to the outer circumference of the partition 20. The number of through holes 22b is less than the number of through holes 22a. The number of through holes 22b is preferably 50% to 90% of the number of through holes 22a, and more preferably 60% to 80%.

[0017] The array pitch p2 of the through-holes 22b is larger than the array pitch p1 of the through-holes 22a. Here, the array pitch p1 is defined as the center-to-center distance between the closest through-holes 22a on the upper surface of the partition portion 20. Similarly, the array pitch p2 is defined as the center-to-center distance between the closest through-holes 22b on the upper surface of the partition portion 20. The array pitch p2 is preferably 1.5 times or more, and more preferably 2 times or more, of the array pitch p1. In the present embodiment, the opening areas of the plurality of through-holes 22 are equal to each other. Here, the opening area is defined as the area of the opening portion when each through-hole 22 is viewed in plan (see FIG. 5). Therefore, the opening area of each through-hole 22b is equal to the opening area of each through-hole 22a. Further, the plurality of through-holes 22 are congruent with each other. That is, the plurality of through-holes 22 are composed of congruent cylindrical spaces. Therefore, each through-hole 22b is congruent with each through-hole 22a.

[0018] The plurality of through-holes 22a and the plurality of through-holes 22b are provided in the central portion 20a and the peripheral portion 20b of the partition portion 20, respectively. All the through-holes 22a are provided in the central portion 20a, and all the through-holes 22b are provided in the peripheral portion 20b. The central portion 20a is a portion surrounded by the smallest virtual rectangle R1 that can enclose all the through-holes 22a in plan view. The long side and the short side of the rectangle R1 are parallel to the long side and the short side of the partition portion 20, respectively. In plan view, the center of the central portion 20a coincides with the center of the partition portion 20. The peripheral portion 20b is a portion other than the central portion 20a in the partition portion 20 and surrounds the entire central portion 20a. The area ratio of the central portion 20a in the partition portion 20 in plan view is preferably 20% or more and 60% or less, and more preferably 30% or more and 50% or less.

[0019] In the upper space S1 of the main body portion 10, a plurality of granular bodies 30 for treating excrement (mainly urine) are laid. The plurality of granular bodies 30 are laid directly on the partition portion 20. Each granular body 30 has a granular shape. Examples of such granular shapes include a sphere, a cylinder, or an ellipsoid. The particle size of each granular body 30 is, for example, 5 mm or more and 30 mm or less. Here, the particle size of the granular body 30 is defined as the diameter of the smallest sphere that can enclose the granular body 30. When the animal toilet 1 is in use, the granular body 30 will directly receive excrement.

[0020] The granular body 30 has hydrophobicity. That is, the granular body 30 has the property of not absorbing any liquid such as urine at all, or hardly absorbing it even if it does absorb. Unlike the granular body having water absorption, such a hydrophobic granular body 30 does not adhere to each other and form a solid mass when wet with urine.

[0021] For the granular body 30 to have hydrophobicity, it is necessary that the liquid passing rate measured by the following test is 60% or more. First, put 50 g equivalent of the granular body 30 (sample) into a sieve with an inner diameter of 10 cm and a mesh size of 1 mm. An empty beaker is placed under the sieve. Then, using a syringe (Terumo 60 ml syringe) with an outer cylinder inner diameter of 3 cm and a cylinder tip inner diameter of 4 mm, 30 ml of water is dropped onto the sample over 10 seconds. After leaving it for 1 minute, measure the amount of water in the beaker. The ratio of the measured amount of water to the dropped amount of water (30 ml) is taken as the liquid passing rate. At this time, if the amount of water in the beaker is 18 ml or more, the liquid passing rate is 60% or more, so it can be said that the granular body 30 has hydrophobicity.

[0022] It is preferable that each granular body 30 has an organic substance as the main material. Here, the main material of the granular body 30 refers to the one with the largest weight ratio in the granular body 30 among one or more materials constituting the granular body 30. Examples of such organic substances include papers, plants, plastics, or organic sludges. Each granular body 30 may consist only of an organic substance, or may consist of an organic substance and an inorganic substance.

[0023] Paper refers to materials primarily composed of pulp. Examples of paper include, for example, ordinary paper (paper dust), photographic paper, release paper, fluff pulp, paper derived from vinyl wallpaper (paper generated during the manufacture or classification of vinyl wallpaper), paper derived from gypsum board (paper generated during the manufacture or classification of gypsum board), or paper derived from sanitary products (paper generated during the manufacture or classification of sanitary products containing paper). Examples of sanitary products containing paper include disposable diapers, sanitary napkins, incontinence pads, or sanitary paper (tissue paper, toilet paper, paper towels, etc.). Examples of plant materials include, for example, wood powder, sawdust, or plant residues (tea leaves, okara, etc.). Examples of plastics include, for example, ordinary plastics, aluminum-metallized film, plastic derived from vinyl wallpaper (plastic generated during the manufacture or classification of vinyl wallpaper), or plastic derived from sanitary products (plastic generated during the manufacture or classification of sanitary products containing plastic). Examples of sanitary products containing plastic include disposable diapers, sanitary napkins, incontinence pads, or sanitary masks. Examples of organic sludges that can be used include papermaking sludge or pulp sludge. These materials may or may not be treated with hydrophobic (water-repellent) treatment.

[0024] The granular material 30 may consist of only one material or two or more materials. In the former case, the granular material 30 will consist only of the main material described above. In the latter case, the granular material 30 will be composed of a mixture of the main material and other materials. Examples of other materials include gypsum or baking soda. Adding gypsum or baking soda makes it easier to impart hydrophobicity to the granular material 30. The proportion of gypsum or baking soda is, for example, 5% by weight or more and less than 50% by weight of the total granular material 30.

[0025] The granular material 30 can be manufactured, for example, by the following method. First, granulation is performed on the granulating material (the material constituting the granular material 30) using a granulation apparatus to form granules that will become the granular material 30. For example, an extruder can be used as the granulation apparatus. The granules may be subjected to hydrophobic treatment as needed. Hydrophobic treatment can be performed, for example, by coating the surface of the granules with a hydrophobic agent (water repellent). If hydrophobic treatment is not performed, it is preferable to increase the pressure applied to the granulating material during granulation to minimize the formation of gaps within the granules. This is because such gaps become pathways for liquids such as urine to penetrate into the interior of the granular material 30. Prior to granulation, pre-treatment such as crushing, kneading, and hydration is performed on the granulating material as needed. After granulation, post-treatment such as sieving (separation) and drying is performed as needed.

[0026] An absorbent sheet 40 is placed in the lower space S2 of the main body 10. The absorbent sheet 40 absorbs urine that passes through the through-hole 22 of the partition 20. In other words, urine that passes through the through-hole 22 is absorbed by the absorbent sheet 40 and accumulates in the lower space S2.

[0027] Figure 6 is a perspective view showing the drawer section 50. The drawer section 50 has a bottom plate 50a, a front plate 50b, an end plate 50c, and a pair of side plates 50d. The size of the bottom plate 50a is approximately equal to the size of the bottom surface 10a of the main body section 10. The front plate 50b has approximately the same shape and size as the opening 12. A handle 52 is attached to the front plate 50b. The drawer section 50 can be inserted into and removed from the main body section 10 through the opening 12. An absorbent sheet 40 is housed in the drawer section 50. That is, the absorbent sheet 40 is disposed inside the main body section 10 while housed in the drawer section 50. For example, plastic can be used as the material for the drawer section 50.

[0028] When the animal toilet 1 is used, the urine excreted in the main body 10 passes through the gaps between the granular materials 30 and then moves from the upper space S1 to the lower space S2 through the through-holes 22 of the partition 20. The urine that moves to the lower space S2 is absorbed by the absorbent sheet 40.

[0029] The effects of animal toilet 1 are explained below. In animal toilet 1, through holes 22a and 22b are provided in the partition 20. Through holes 22b are located further out than through holes 22a. The arrangement pitch p2 of through holes 22b is larger than the arrangement pitch p1 of through holes 22a. By making the arrangement pitch p2 of the through holes 22b, which are located relatively further out, larger, odors generated from urine accumulated in the lower space S2 are less likely to leak into the upper space S1. This is because odors tend to rise, especially along the side surface 10b of the main body 10, and are therefore more likely to pass through through holes 22b, which are located relatively further out, than through holes 22a, which are located relatively further in. On the other hand, by making the arrangement pitch p1 of the through holes 22a, which are located relatively further in, smaller, urine can move more smoothly from the upper space S1 to the lower space S2. Therefore, animal toilet 1 is realized that is suitable for suppressing the leakage of odors from the lower space S2 to the upper space S1 without hindering the smooth movement of urine from the upper space S1 to the lower space S2.

[0030] From the viewpoint of suppressing odor leakage without hindering the smooth movement of urine, the arrangement pitch p2 of the through-holes 22b is preferably 1.5 times or more, and more preferably 2 times or more, than the arrangement pitch p1 of the through-holes 22a. On the other hand, if the arrangement pitch p2 is too large, the number of through-holes 22b will be extremely small, which may hinder the movement of urine from the upper space S1 to the lower space S2 through the through-holes 22b. From this viewpoint, the arrangement pitch p2 is preferably 3 times or less of the arrangement pitch p1.

[0031] The opening area of ​​each through-hole 22b is equal to the opening area of ​​each through-hole 22a. In this case, there is no need to make the opening area of ​​the through-hole 22b smaller than the opening area of ​​the through-hole 22a, thus reducing the likelihood of problems such as urine clogging the through-hole 22b. However, it is not essential that the opening area of ​​each through-hole 22b is equal to the opening area of ​​each through-hole 22a.

[0032] Each through-hole 22b is congruent to each through-hole 22a. By aligning the shapes of the through-holes 22a and 22b in this way, the aesthetic appearance of the partition 20 and, consequently, the animal toilet 1 can be improved. However, it is not essential that each through-hole 22b is congruent to each through-hole 22a.

[0033] The partition 20 is flat. This makes it easy to mold the partition 20. This contributes to reducing the manufacturing cost of the partition 20 and, consequently, the animal toilet 1.

[0034] Multiple through-holes 22a are provided in the central part 20a of the partition 20, and multiple through-holes 22b are provided in the peripheral part 20b of the partition 20. By neatly distinguishing the area where the through-holes 22a are located from the area where the through-holes 22b are located in this way, the aesthetic appearance of the partition 20 and, consequently, the animal toilet 1 can be improved.

[0035] Reducing the area of ​​the central portion 20a, which is provided with through-holes 22a having a relatively small arrangement pitch p1, is advantageous in suppressing the leakage of odor from the lower space S2 to the upper space S1. From this viewpoint, the area ratio of the central portion 20a to the partition portion 20 in a plan view is preferably 60% or less, and more preferably 50% or less. On the other hand, if the area of ​​the central portion 20a is too small, it becomes difficult for urine to move smoothly from the upper space S1 to the lower space S2. From this viewpoint, the above area ratio is preferably 20% or more, and more preferably 30% or more.

[0036] The number of through-holes 22b is less than the number of through-holes 22a. By reducing the number of through-holes 22b in this way, the leakage of odor from the lower space S2 to the upper space S1 can be effectively suppressed. From this viewpoint, the number of through-holes 22b is preferably 90% or less of the number of through-holes 22a, and more preferably 80% or less. On the other hand, if the number of through-holes 22b is too small, it may hinder the movement of urine from the upper space S1 to the lower space S2 through the through-holes 22b. From this viewpoint, the number of through-holes 22b is preferably 50% or more of the number of through-holes 22a, and more preferably 60% or more.

[0037] The granular material 30 is hydrophobic. In this case, most of the urine excreted on the granular material 30 is not absorbed by the granular material 30, but passes through the gaps between the granular material 30. This allows the urine to be quickly guided to the lower space S2.

[0038] When each granular material 30 is primarily made of organic matter, it is possible to obtain granular materials 30 suitable for incineration. This contributes to the convenience of disposing of used granular materials 30. In particular, when each granular material 30 consists solely of organic matter, it is possible to obtain granular materials 30 that are even more suitable for incineration.

[0039] The main body 10 consists of a single container. In this case, an animal toilet 1 having an upper space S1 and a lower space S2 can be realized with a simpler configuration compared to when the main body 10 consists of multiple containers.

[0040] The partition 20 is not fixed to the main body 10. In this case, it becomes easy to attach and detach the partition 20 from the main body 10.

[0041] The partition 20 is placed on the support 14. This allows the partition 20 to be kept in a predetermined position within the main body 10 without being fixed to the main body 10.

[0042] The support portion 14 is provided along the entire inner circumference of the side portion 10b in a plan view. This makes it easier to prevent the partition portion 20 from falling into the lower space S2.

[0043] The partition 20 can be installed inside the main body 10 with its entire perimeter separated from the side portion 10b. By providing a margin between the partition 20 and the side portion 10b in this way, the partition 20 can be smoothly attached to and detached from the main body 10.

[0044] An absorbent sheet 40 is placed in the lower space S2. This allows the urine accumulated in the lower space S2 to be contained within the absorbent sheet 40. As a result, the generation of unpleasant odors from the urine can be mitigated.

[0045] A drawer section 50 is provided that can be inserted into and removed from the main body section 10. This makes it easy to replace a used absorbent sheet 40 with a new one.

[0046] Incidentally, unlike other animals such as dogs, cats have the habit of concealing their excrement with granular material after defecating. Therefore, an animal toilet 1 in which multiple granular materials 30 are laid in the upper space S1 can be used particularly suitably as a cat toilet.

[0047] The present invention is not limited to the above embodiment, and various modifications are possible. In the above embodiment, an example was given in which two types of through holes 22 (through holes 22a and through holes 22b) with different arrangement pitches are provided in the partition portion 20. However, the partition portion 20 may have three or more types of through holes 22 with different arrangement pitches, as shown in Figure 7, for example. In the same figure, the partition portion 20 has a plurality of through holes 22a and a plurality of through holes 22b, as well as a plurality of through holes 22c (third through holes). The through holes 22c are located outside the through holes 22b. The arrangement pitch p3 of the through holes 22c is greater than the arrangement pitch p2 of the through holes 22b. The opening area of ​​each through hole 22c is equal to the opening area of ​​each through hole 22a and the opening area of ​​each through hole 22b. Each through hole 22c is congruent to each through hole 22a and each through hole 22b.

[0048] The through holes 22c are provided in the peripheral portion 20c of the partition portion 20. All of the through holes 22c are provided in the peripheral portion 20c. In this example, the peripheral portion 20b (first peripheral portion) is the portion enclosed by the smallest hypothetical rectangle R2 that can contain all the through holes 22b in a plan view, excluding the central portion 20a. The long and short sides of the rectangle R2 are parallel to the long and short sides of the partition portion 20, respectively. The peripheral portion 20c (second peripheral portion) is the portion of the partition portion 20 other than the central portion 20a and the peripheral portion 20b, and surrounds the entire peripheral portion 20b.

[0049] In the above embodiment, the case where the number of through holes 22b is less than the number of through holes 22a was illustrated. However, the number of through holes 22b may be equal to the number of through holes 22a, or it may be greater than the number of through holes 22a.

[0050] In the above embodiment, the case where the planar shape of the through-hole 22 is circular was illustrated. However, the planar shape of the through-hole 22 is arbitrary and may be, for example, elliptical or polygonal, such as a rectangle.

[0051] In the above embodiment, the case in which a drawer portion 50 is provided is illustrated. However, providing the drawer portion 50 is not essential. If the drawer portion 50 is not provided, the absorbent sheet 40 is placed directly on the bottom portion 10a. In that case, naturally, the opening 12 is not provided on the side portion 10b.

[0052] In the above embodiment, an example was given in which an absorbent sheet 40 is provided on the main body 10. However, it is not essential to provide the absorbent sheet 40 on the main body 10. If the absorbent sheet 40 is not provided, the drawer portion 50 will not be provided either.

[0053] In the above embodiment, an example was given in which the main body 10 is composed of one container. However, the main body 10 may be composed of multiple containers, for example, as shown in Figure 8. In the same figure, the main body 10 is composed of two containers (containers 62 and 64). Each container 62 and 64 is box-shaped with a bottom and side surfaces. Container 62 is stacked on top of container 64. The bottom surface of container 62 has a through hole 22, which constitutes a partition 20. As a result, the internal space of container 62 and the internal space of container 64 become the upper space S1 and the lower space S2, respectively. Furthermore, the bottom surface of container 64 constitutes the bottom surface of the main body 10, and the side surfaces of container 62 and container 64 constitute the side surfaces of the main body 10.
