[0001] The present invention relates to an animal litter box. Background Art

[0002] As a conventional animal litter box, for example, there is one described in Patent Document 1. The animal litter box described in said document includes a main body (tray) that receives excreted urine, and a partition (grid) that divides the internal space of the main body into an upper space and a lower space. The partition has through holes that allow urine to pass through. In the upper space (on the partition), a plurality of low water-absorbent granular materials are laid. In the lower space, a water-absorbent sheet that absorbs urine is disposed. Prior Art Literature Patent Literature

[0003] Patent Document 1 Japanese Patent Application Laid-Open No. 2003-180182 Summary of the Invention Problem to be Solved by the Invention

[0004] In the above-described animal litter box, animals defecate and urinate within the upper space. The excreted urine passes through the gaps between the granular materials, 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 is accumulated in the lower space while being absorbed by the water-absorbent sheet. Therefore, there is a problem that odor generated from urine is easily trapped in the lower space. Part of the odor trapped in the lower space rises to the upper space through the through holes. This causes discomfort to the animal while it is excreting in the upper space, and may become a factor that makes the animal reluctant to defecate in the animal litter box.

[0005] The present invention has been made in view of the above problems, and an object of the present invention is to provide an animal litter box in which the odor of urine is less likely to be trapped in the lower space of the main body. Means for Solving the Problem

[0006] The animal toilet according to the present invention is characterized by comprising: a main body having a bottom and side portions for receiving excreted urine; a partition having a through hole for the urine to pass through, which divides the internal space of the main body into an upper space and a lower space; and a ventilation device provided below the partition for ventilating the lower space.

[0007] In this animal litter box, a ventilation device is installed below the partition. The ventilation device allows for ventilation of the lower space. Therefore, even if an odor is generated from urine accumulated in the lower space, the odor is less likely to linger in that space. [Effects of the Invention]

[0008] According to the present invention, an animal toilet is realized in which the odor of urine is less likely to accumulate in the lower space of the main body. [Brief explanation of the drawing]

[Figure 6] This is a plan view showing the partition section 20. [Figure 7] This is a perspective view showing the drawer section 60. [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 ventilation device 30, a plurality of granular materials 40, an absorbent sheet 50, and a drawer 60. 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 bottom surface 10a is substantially rectangular in plan view. Here, substantially rectangular does not mean not only a rectangle, but also shapes close to a rectangle, such as a rounded quadrilateral. The side surfaces 10b consist of four side walls connected to each of the four sides of the bottom surface 10a. 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] Figure 2 is an end view showing the main body 10. Figures 3 and 4 are side views showing the main body 10. An opening 12 (first opening) and an opening 14 (second opening) are formed in the side portion 10b of the main body 10. The opening 12 is formed in a different side wall from the side wall on which the opening 14 is formed among the four side walls that make up the side portion 10b. The side wall on which the opening 12 is formed (see Figure 3) faces the side wall on which the opening 14 is formed (see Figure 4). The opening 12 functions as an outlet for discharging air from the internal space of the main body 10. In this embodiment, the opening 12 is circular. The diameter of the opening 12 is, for example, 5 cm or more and 10 cm or less. In the height direction of the main body 10 (up and down direction in Figures 1 to 4), the entire opening 12 is located between the support portion 16 (described later) and the front plate 60c of the pull-out portion 60. That is, the height of the upper end of the opening 12 is less than or equal to the height of the lower end of the support portion 16. Furthermore, the height of the lower end of the opening 12 is greater than or equal to the height of the upper end of the front plate 60c. Here, "height" is defined as the distance from the floor surface in the height direction of the main body 10.

[0013] The opening 14 is provided for inserting and removing the drawer 60 from the main body 10. The opening 14 is located near the bottom surface 10a and has a horizontally elongated rectangular shape. The length of the opening 14 in the horizontal direction (left-right direction in Figure 4) 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 14 in the vertical direction (up-down direction in Figure 4) is for example, 2 cm or more and 5 cm or less.

[0014] Figure 5 is a plan view showing the main body 10. The main body 10 has a support portion 16. The support portion 16 protrudes inward from the side portion 10b of the main body 10. The support portion 16 supports the partition portion 20 from below. In plan view, the support portion 16 is provided along the entire inner circumference of the side portion 10b. That is, the support portion 16 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. The protruding length of the support portion 16 (length in the direction perpendicular to the inner surface of the side wall on which the support portion 16 is provided) is, for example, 5 mm or more and 15 mm or less. The support portion 16 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. Note that in the animal toilet 1, the top of the main body 10 is not covered. That is, there is no hood or the like that covers the top of the main body 10.

[0015] Figure 6 is a plan view showing the partition 20. The partition 20 is placed on the support 16. 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 surface 10b. The partition 20 is made of a plate-shaped member. 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 surface 10b) and the absorbent sheet 50. 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 40 are laid. The lower space S2 is located below the partition 20 and is a space where urine accumulates. For example, plastic can be used as the material for the partition 20.

[0016] The partition section 20 has through-holes 22 through which urine can pass. The through-holes 22 allow urine to pass through but prevent each granular material 40 from passing through. The partition section 20 has a plurality of through-holes 22. The plurality of through-holes 22 are arranged in a grid pattern in the partition section 20. The planar shape of each through-hole 22 is circular. The diameter of each through-hole 22 is, for example, 2 mm to 10 mm.

[0017] The ventilation device 30 is provided below the partition part 20. The ventilation device 30 is attached to the main body part 10. The ventilation device 30 is a device for ventilating the lower space S2 of the main body part 10. The ventilation device 30 is configured to discharge air from the lower space S2 through the opening 12. In this embodiment, the ventilation device 30 includes an impeller disposed in the opening 12. Note that in Fig. 3, in addition to the main body part 10, the ventilation device 30 (impeller) is also illustrated. The ventilation device 30 discharges air from the lower space S2 to the outside of the animal toilet 1 by rotating the impeller to generate an outward air flow (air flow directed from the inside of the main body part 10 to the outside) in the opening 12. A net-like cover (not shown) is provided outside the impeller (between the impeller and the outside of the main body part 10) to prevent animals or people from touching the impeller. The cover is attached to the side part 10b. The ventilation device 30 may include a filter having a deodorizing function or a deodorization function. The filter may be provided outside the impeller, or may be provided inside (between the impeller and the lower space S2). In the former case, the position of the filter may be outside or inside the cover.

[0018] The on / off switching of the ventilation device 30 can be manually performed by a switch (not shown). The switch is provided, for example, on the outer surface of the side part 10b. As a power source for operating the ventilation device 30, an outlet may be used, or a battery may be used.

[0019] The animal litter box 1 may be provided with a sensor that detects when an animal enters or exits the animal litter box 1. In this case, it is preferable that the ventilation device 30 is controlled such that on / off switching is automatically performed in conjunction with the sensor. As the sensor, for example, a human motion sensor or a weight sensor can be used. The human motion sensor detects the movement of an animal in the upper space S1 by means of infrared rays or the like. The human motion sensor is provided, for example, on the inner surface of the side portion 10b. The weight sensor detects a change in weight applied to the main body portion 10. Specifically, the weight sensor detects whether or not the weight applied to the main body portion 10 (excluding the weight of the partition portion 20, the ventilation device 30, the granular material 40, the water-absorbent sheet 50, and the drawer portion 60) is equal to or greater than a threshold value. The threshold value is set to a value that is larger than the weight of excrement accumulated in the main body portion 10 and smaller than the body weight of the animal that uses the animal litter box 1. The weight sensor is provided, for example, on the bottom surface portion 10a.

[0020] For example, the ventilation device 30 may be controlled to be turned on when the sensor detects that an animal has entered the animal litter box 1. Alternatively, the ventilation device 30 may be controlled to be turned on when the sensor detects that an animal has exited the animal litter box 1. Further, the ventilation device 30 may be controlled to be turned off after a certain period of time (for example, 5 to 30 minutes) has elapsed since the sensor detected that the animal exited the animal litter box 1. It is preferable that the control circuit of the ventilation device 30 is built into the main body portion 10. For example, it is conceivable that the side portion 10b has a double structure consisting of an outer plate (a plate constituting the outer surface of the side portion 10b) and an inner plate (a plate constituting the inner surface of the side portion 10b), and the control circuit is disposed in the space between them.

[0021] Multiple granular materials 40 for processing excrement (mainly urine) are laid in the upper space S1 of the main body 10. The multiple granular materials 40 are laid directly on the partition 20. Each granular material 40 is granular in shape. Examples of such granular shapes include spheres, cylinders, or ellipsoids. The particle size of each granular material 40 is, for example, 3 mm to 30 mm. Here, the particle size of the granular material 40 is defined as the diameter of the smallest sphere that can contain the granular material 40. When the animal toilet 1 is used, the granular materials 40 will directly receive the excrement.

[0022] The granular material 40 is hydrophobic. That is, the granular material 40 does not absorb liquids such as urine at all, or absorbs very little. Unlike granular material with water absorption properties, the hydrophobic granular material 40 does not stick together and form clumps when wet with urine.

[0023] For granular material 40 to be hydrophobic, the liquid permeability measured by the following test must be 60% or higher. First, place 50g of granular material 40 (sample) into a sieve with an inner diameter of 10cm and a mesh size of 1mm. Place an empty beaker below the sieve. Then, using a syringe with an outer cylinder inner diameter of 3cm and a tip inner diameter of 4mm (Terumo 60ml syringe), dropwise add 30ml of water to the sample over 10 seconds. After standing for 1 minute, measure the amount of water in the beaker. The liquid permeability is calculated as the ratio of the measured amount of water to the amount of water added (30ml). If the amount of water in the beaker is 18ml or more, the liquid permeability is 60% or higher, and therefore, granular material 40 can be said to be hydrophobic.

[0024] Each granular material 40 is preferably made primarily of organic matter. Here, the main material of the granular material 40 refers to the material that accounts for the largest weight percentage of the granular material 40 among the one or more materials that make up the granular material 40. Examples of such organic matter include paper, plants, plastics, or organic sludge. Each granular material 40 may consist only of organic matter, or it may consist of organic matter and inorganic matter.

[0025] 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.

[0026] The granular material 40 may consist of only one material or two or more materials. In the former case, the granular material 40 will consist only of the main material described above. In the latter case, the granular material 40 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 40. 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 40.

[0027] The granular material 40 can be manufactured, for example, by the following method. First, granulation is performed on the granulating material (the material constituting the granular material 40) using a granulation apparatus to form granules that will become the granular material 40. 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 40. 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.

[0028] An absorbent sheet 50 is placed in the lower space S2 of the main body 10. The absorbent sheet 50 absorbs urine that passes through the through-holes 22 of the partition 20. In other words, urine that passes through the through-holes 22 is absorbed by the absorbent sheet 50 and accumulates in the lower space S2.

[0029] Figure 7 is a perspective view showing the drawer section 60. The drawer section 60 has a bottom plate 60a, a front plate 60b, an end plate 60c, and a pair of side plates 60d. The size of the bottom plate 60a is approximately equal to the size of the bottom surface 10a of the main body section 10. The front plate 60b has approximately the same shape and size as the opening 14. A handle 62 is attached to the front plate 60b. The drawer section 60 can be inserted into and removed from the main body section 10 through the opening 14. An absorbent sheet 50 is housed in the drawer section 60. That is, the absorbent sheet 50 is disposed inside the main body section 10 while housed in the drawer section 60. For example, plastic can be used as the material for the drawer section 60.

[0030] When the animal toilet 1 is used, the urine excreted in the main body 10 passes through the gaps between the granular materials 40 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 50.

[0031] The effects of the animal toilet 1 are explained below. In the animal toilet 1, a ventilation device 30 is provided below the partition 20. The ventilation device 30 makes it possible to ventilate the lower space S2. Therefore, even if an odor is generated from the urine accumulated in the lower space S2, the odor is less likely to linger in the lower space S2. Thus, the animal toilet 1 is realized in which the odor of urine is less likely to linger in the lower space S2 of the main body 10.

[0032] Furthermore, the ventilation device 30 can draw air from the upper space S1 into the lower space S2 through the through-hole 22 of the partition 20. This makes it possible to prevent odors from spreading into the upper space S1, even if odors are generated from urine remaining in the upper space S1 (for example, urine attached to the granular material 40). In addition, because the ventilation device 30 is located below the partition 20, compared to the case where the ventilation device 30 is located above the partition 20, there is an advantage that the effects (for example, sound and wind) of operating the ventilation device 30 during excretion are less likely to be transmitted to the animal.

[0033] An opening 12 is formed in the side portion 10b. The ventilation device 30 is configured to discharge air from the lower space S2 through the opening 12. This allows air from the lower space S2 to be discharged directly to the outside of the main body 10 without passing through the upper space S1.

[0034] The ventilation device 30 includes an impeller disposed within the opening 12. This allows for a ventilation device 30 that discharges air from the lower space S2 through the opening 12 with a simple configuration.

[0035] If the ventilation device 30 includes a filter with a deodorizing or odor-removing function, it can mitigate malodorous odors contained in the air discharged to the outside of the main unit 10.

[0036] The ventilation device 30 is attached to the main body 10. This makes it possible to create an animal toilet 1 that has the function of ventilating the lower space S2 without having to retrofit a ventilation device to the animal toilet 1.

[0037] If the ventilation device 30 is controlled to automatically switch on and off in conjunction with the aforementioned sensor, it becomes possible to switch the ventilation device 30 on and off at the appropriate time without manual operation by a person (pet owner).

[0038] If the ventilation device 30 is controlled to turn on when a sensor detects that an animal has entered the animal toilet 1, ventilation will occur even while the animal is defecating, allowing the animal to defecate more comfortably.

[0039] If the ventilation device 30 is controlled to turn on when a sensor detects that an animal has left the animal toilet 1, the odor immediately after defecation can be discharged from the lower space S2. On the other hand, since ventilation does not occur during defecation, animals can defecate with peace of mind even if they dislike even the slightest effect of the ventilation device 30 operating.

[0040] If the ventilation device 30 is controlled to turn off after a certain period of time has elapsed since the sensor detected that an animal had left the animal litter box 1, it is possible to prevent the ventilation device 30 from operating for an unnecessarily long time, thus contributing to energy saving.

[0041] If the above sensor is a motion sensor, it is possible to create a low-cost sensor that detects when an animal enters or leaves the animal toilet 1.

[0042] If the above sensor is a weight sensor, it is possible to realize a sensor that can detect with high accuracy when an animal enters or leaves the animal toilet 1.

[0043] The upper part of the main body 10 is not covered by a hood or the like. In this case, even animals that dislike hoods or animals that have the habit of placing their front paws on the edge of the main body 10 (the upper end of the side part 10b) to defecate can easily use the animal toilet 1. However, the animal toilet 1 may be equipped with a hood or the like that covers the upper part of the main body 10.

[0044] The granular material 40 is hydrophobic. In this case, most of the urine excreted on the granular material 40 is not absorbed by the granular material 40, but passes through the gaps between the granular material 40. This allows the urine to be quickly guided to the lower space S2.

[0045] When each granular material 40 is primarily made of organic matter, granular materials 40 suitable for incineration can be obtained. This contributes to the convenience of disposing of used granular materials 40. In particular, when each granular material 40 consists solely of organic matter, granular materials 40 that are even more suitable for incineration can be obtained.

[0046] 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.

[0047] 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.

[0048] The partition 20 is placed on the support 16. 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.

[0049] The support portion 16 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.

[0050] 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.

[0051] An absorbent sheet 50 is placed in the lower space S2. This allows the urine accumulated in the lower space S2 to be contained within the absorbent sheet 50. As a result, the generation of odor from the urine can be mitigated.

[0052] A drawer section 60 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 50 with a new one.

[0053] 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 40 are laid in the upper space S1 can be used particularly suitably as a cat toilet.

[0054] The present invention is not limited to the above embodiments, and various modifications are possible. In the above embodiments, an example was given in which the opening 12 for the ventilation device 30 is formed in the side wall opposite to the opening 14 for the drawer portion 60 (the side wall facing the front plate 60c). However, the opening 12 may be formed in the same side wall as the opening 14, or in a different side wall (the side wall facing the side plate 60d).

[0055] 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.

[0056] In the above embodiment, the case in which a drawer portion 60 is provided is illustrated. However, providing the drawer portion 60 is not essential. If the drawer portion 60 is not provided, the absorbent sheet 50 is placed directly on the bottom portion 10a. In that case, naturally, the opening 14 is not provided on the side portion 10b.

[0057] In the above embodiment, an example was given in which an absorbent sheet 50 is provided on the main body 10. However, it is not essential to provide the absorbent sheet 50 on the main body 10. If the absorbent sheet 50 is not provided, the drawer portion 60 will not be provided either.

[0058] 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 72 and 74). Each container 72 and 74 is box-shaped with a bottom and side surfaces. Container 72 is stacked on top of container 74. The bottom surface of container 72 has a through hole 22, which constitutes a partition 20. As a result, the internal space of container 72 and the internal space of container 74 become the upper space S1 and the lower space S2, respectively. Furthermore, the bottom surface of container 74 constitutes the bottom surface of the main body 10, and the side surfaces of container 72 and container 74 constitute the side surfaces of the main body 10.
