Description

  The present invention relates to an animal toilet provided with a support having a mesh on the bottom surface through which urine passes when an animal urinates, and a holder for holding urine provided below the support.

  Conventional household pet toilets consist of containers containing cat litter. In such a pet toilet, once every one or two weeks, the cat litter in the container must be discarded, the container must be washed, and new cat litter must be replaced. As a result, it takes time and effort to wash, and a large amount of cat litter is discarded as garbage.

  In order to solve such a problem, for example, in the conventional pet toilet 100 disclosed in Patent Document 1, as shown in FIGS. A water-repellent granular material 112 is placed in a container 110. Below the sheet 111 at the bottom of the container 110, a liquid absorbing sheet 121 supported by a support body 120 is provided in close contact with the sheet 111. Urine passes through the water-repellent granular material 112, passes through the sheet 111 at the bottom of the container 110, and is absorbed by the absorbent sheet 121.

  As a result, no urine remains in the container 110. In addition, cleaning of the pet litter box 100 only requires replacement of the liquid absorbing sheet 121 once a day, and replacement of all the granular materials 112 once every one or two months can be performed without any hassle. The amount can be reduced.

JP-A-10-229768 (published on September 2, 1998)

  However, in the above-mentioned conventional pet litter box 100, pets such as cats do not necessarily urinate near the center of the liquid absorbing sheet 121. For this reason, in the conventional structure, when urinating at the end of the toilet, the urine is directly dropped onto the end of the liquid absorbing sheet 121 through the liquid-permeable sheet 111. As a result, for example, the amount of urine absorbed by the liquid absorbing sheet 121 in the support body 120 is measured by a weighing scale with the central area of the liquid absorbing sheet 121 as a measurement center while keeping the structure of the conventional pet toilet. In such a case, the weight of the liquid absorbing sheet 121 at the end becomes unbalanced and heavier, so that there is a problem that a measurement error increases.

  The present invention has been made in view of the above-described conventional problems, and its purpose is to measure urine held in a holder with a central region of the holder as a measurement center using a weighing scale, An object of the present invention is to provide an animal litter box capable of reducing measurement errors even when an animal urinates at an end of a support table.

  In order to solve the above problems, the animal litter box according to one embodiment of the present invention includes a support having a mesh on the bottom surface through which urine passes when the animal urinates, and the support under the support has In an animal litter box provided with a holding body for holding urine, a weighing scale for measuring urine held in the holding body is provided, and the mesh is provided with the urine in a central region of the holding body. It is characterized by comprising a plurality of slits formed on the bottom surface of the support base so as to fall.

  According to one aspect of the present invention, when measuring urine held in the holder with the central region of the holder as a measurement center using a weighing scale, even if the animal urinates at the end of the support, There is an effect of providing an animal litter box that can reduce measurement errors.

[Embodiment 1]
One embodiment of the present invention will be described below with reference to FIGS.

  The pet toilet as the animal toilet according to the present embodiment is used when pets such as cats and dogs, which are domestic animals, urinate. However, the animal litter box of the present invention is not necessarily limited to animals such as cats and dogs, and can be applied to other animals.

  In the present embodiment, a pet toilet having a function of measuring the amount of urination and the number of times of urination for health management of a pet will be described.

  A configuration of a pet toilet as an animal toilet according to the present embodiment will be described with reference to FIGS. FIG. 1 is an exploded perspective view showing a configuration of the pet toilet 1 according to Embodiment 1 from which a cover 14 is removed. FIG. 2A is a plan view showing the entire configuration of the pet toilet 1, and FIG. 2B is a left side view showing the entire configuration of the pet toilet 1, and FIG. 2) is a right side view showing the entire configuration of the pet toilet 1, and FIG. 2D is a front view showing the entire configuration of the pet toilet 1. FIG. 3 is a perspective view showing a configuration of the pet toilet 1 excluding the cover 14. FIG. 4 is an exploded perspective view showing a configuration of the slide frame 17 and the excretion tray 16 of the pet toilet 1. FIG. 5 is a front sectional view showing the configuration of the pet toilet 1 with the cover 14 removed.

  As shown in FIGS. 2A, 2B, 2C, and 2D and FIG. 3, the pet litter 1 as an animal litter of the present embodiment stands at, for example, four corners of a rectangular support plate 11. The main body container 13 is supported by the standing pillar 12 to be provided, and a cover 14 provided as a lid of the main body container 13 is provided. The cover 14 is a cover surrounding four sides of the animal placed on the pet litter 1, but is not limited thereto, and may be, for example, a cover surrounding three sides. A weighing scale 15 is provided at the center of the support plate 11.

  As shown in FIG. 1, a support base 20 (a support base for supporting an animal) on which a pet, which is an animal, is provided inside the main body container 13, and an excretion tray 16 is provided below the support base 20. The mounted slide frame 17 is provided so as to be inserted into the main body container 13. The support 20 may be filled with a filler such as water-repellent gravel, sand, or glass beads. Further, the support base 20 itself may have water repellency so that the urine easily flows so that the urine does not adhere and accumulate. Note that a configuration in which the animal is placed on another member supported by the support base 20 may be employed.

  As shown in FIG. 4, the slide frame 17 on which the excretion tray 16 is placed is formed in a square frame shape with an opening 17a at the center, and the excretion tray 16 is mounted thereon. . An absorbent sheet 18 as a holding body is laid on the excretion tray 16. The absorbent sheet 18 is preferably, for example, one having high water absorbency containing a water absorbent resin. However, the holding body of the present invention is not limited to this, and can absorb liquid such as sponge or paper. Anything should do.

  As shown in FIG. 1, the slide frame 17 on which the excretion tray 16 on which the absorbent sheet 18 is spread is placed into the main body container 13 through a side opening 13a formed on the side surface of the main body container 13. On the other hand, on the bottom surface of the main body container 13, a weighing scale through hole 13 b is formed substantially at the center, and when the main body container 13 is placed on the upright column 12, the weighing scale 15 is 13b so as to protrude into the main body container 13.

  As a result, when the slide frame 17 on which the excretion tray 16 on which the absorbent sheet 18 is spread is placed and inserted into the main body container 13 through the side opening 13a, the excretion tray 16 is placed on the weight scale 15 as shown in FIG. Upon climbing, the excretion tray 16 supported by the slide frame 17 is lifted, and the excretion tray 16 is supported by the weighing scale 15. Therefore, the weight of the urine absorbed by the absorbent sheet 18 laid on the excretion tray 16 can be measured by the weigh scale 15.

  For example, a cat, a pet, urinates two to three times a day and has a urination volume of 20 to 30 g / kg of body weight per day. Since the weight of an adult cat is 3 to 5 kg, the absorbent sheet 18 usually has a urination amount of 60 to 150 g per day. However, when a disease or the like occurs, the number of urinations and the amount of urination generally tend to decrease. is there. For this reason, in the pet litter box 1 of the present embodiment, the health condition of the cat or the like can be known by measuring the number of times and weight of the pet such as the cat to urinate.

  As a configuration for that, as shown in FIG. 6, the pet toilet 1 of the present embodiment has a control device 30. The configuration of the control device 30 will be described with reference to FIG. FIG. 6 is a block diagram illustrating a configuration of the control device 30 of the pet toilet 1 according to the present embodiment.

  As shown in FIG. 6, the control device 30 includes a power supply unit 31, a sensor driving unit 32, a control unit 33, a storage unit 34, and a communication unit 35.

  In the control device 30 described above, the value of the weight measured by the weigh scale 15 is input to the sensor driving unit 32.

  The power supply unit 31 supplies power to each of the sensor driving units 32, the control unit 33, the storage unit 34, and the communication unit 35 of the control device 30. Note that the power supply unit 31 may be, for example, a battery.

  The sensor drive unit 32 supplies power to the weighing scale 15 to operate the weighing scale 15. In addition, the sensor driving unit 32 receives a measurement value from the weighing scale 15. When detecting that a pet such as a cat has entered the pet litter box 1, the sensor driving unit 32 causes the weight scale 15 to perform measurement. The sensor driver 32 outputs the received measurement value to the controller 33.

  The control unit 33 calculates the weight of urine excreted by a pet such as a cat. Here, in the present embodiment, as an example, the measurement value of the weighing scale 15 represents the entire weight of the absorbent sheet 18 including urine and the excretion tray 16. For this reason, the control unit 33 subtracts the weight of the absorption sheet 18 and the excretion tray 16 that do not absorb urine from the current weight of the absorption sheet 18 and the excretion tray 16 and calculates the urine absorbed by the absorption sheet 18. Find the quantity. The weights of the absorbing sheet 18 and the excretion tray 16 that do not absorb urine are stored in the storage unit 34 in advance. The weight may be a weight measured when the absorbent sheet 18 is replaced.

  Then, data relating to the measured excretion timing and urine weight is stored in the storage unit 34. Alternatively, the data stored in the storage unit 34 may be transmitted from the communication unit 35 to a terminal device owned by the owner such as a cat. Thereby, the owner of the cat or the like can grasp the health condition of the cat or the like by checking the stored excretion timing (frequency) and the weight of the excreted urine.

  As a simple weighing system, for example, a weighing scale 80 shown in FIG. 7A is known.

  As shown in FIG. 7A, the weighing scale 80 includes a load cell 83 formed of a metal rod having a function as a cantilever and having one end 83a fixed to a base 82 provided on a substrate 81. A pedestal 85 is mounted and fixed at an action point 84 provided on the 83b. For example, a strain gauge (not shown) is attached to a surface of the load cell 83 made of the metal bar in the longitudinal direction.

  In the weighing scale 80, a downward force based on the heavy object 86 acts on the application point 84 for the heavy object 86 placed in the center of the pedestal 85, that is, in the vicinity of the application point 84, and the load cell 83 made of a metal rod Then, a bending stress due to the force acting on the point of action 84 acts, so that the bending stress can be detected by the strain gauge and the weight of the heavy object 86 can be calculated.

  However, at this time, when the heavy object 86 is present at the end of the pedestal 85, a rotational moment also acts on the operation point 84 which is a fixed end. For this reason, there is a problem that the value measured by adding the rotational moment has an error with respect to the accurate weight. When the weighing scale 80 is applied to, for example, a kitchen scale, in order to prevent this problem from occurring, for example, the pedestal 85 is made round or ball-shaped so that the weights 86 are gathered near the action point 84. I have.

  Further, as shown in FIG. 7B, a simple weighing scale 90 in which four load cells 92 are mounted on a substrate 91 and a pedestal 93 is mounted on these load cells 92 is also known. In the case of the weighing scale 90, it may not be advantageous that the weighing object is necessarily arranged at the center on the concentric circle.

  However, also in the weighing scale 90, the weighing error is generally adjusted at the center of gravity of the pedestal 93. Therefore, the fact that the weighing object is close to the center of gravity leads to an improvement in weighing accuracy. However, since the weighing scale 90 requires four load cells 92, it is not suitable for a low-cost, high-accuracy system due to a cost problem.

  Also in the pet litter box 1 of the present embodiment, the weighing scale 15 measures the center area of the absorbent sheet 18 as a measurement center.

  For this reason, when the mesh is formed on the entire bottom surface 21 of the support base 20 like the conventional pet toilet 100 disclosed in Patent Document 1 shown in FIGS. When the pet urinates at the end of the support 20, the urine falls through the mesh at that position onto the absorbent sheet 18. As a result, the weight at the end of the absorption sheet 18 becomes unbalanced and heavier, which causes a problem that a measurement error increases.

  Therefore, in the pet toilet 1 of the present embodiment, as shown in FIG. 1, a mesh 22 that allows the urine of the pet to pass through is formed on the bottom surface 21 of the support base 20, and the mesh 22 is made of an absorbent sheet. The center 18 has a plurality of slits 23 formed on the bottom surface 21 of the support base 20 so that urine falls. Specifically, the plurality of slits 23 are formed so as to be at the lowest position on the bottom surface 21 of the support base 20, as shown in FIG. In order to make the plurality of slits 23 at the lowest position on the bottom surface 21 of the support 20, as a specific configuration, the bottom 21 of the support 20 may be a polygonal pyramid such as a triangular pyramid or a quadrangular pyramid. It is conceivable that a triangular pyramid, a truncated polygonal pyramid such as a quadrangular pyramid, or a shape in which the bottom surface 21 of the support base 20 is concave or mortar-shaped and the plurality of slits 23 are at the lowest position. .

  Although the slit 23 is formed in the center of the support base 20 in FIG. 1, the invention is not limited to this, and excrement (urine) drops near the center of the absorption sheet 18 (excretion tray 16). For example, when the absorbing sheet 18 (the excretion tray 16) is arranged not at the center of the support base 20 but at one of the front, rear, left, and right sides, the slit 23 is also adapted to that. It may be formed at a position.

  As a result, even if a pet such as a cat urinates at the end of the support 20, the urine flows into the slits 23 due to the inclination of the support 20, so that the urine falls from these slits 23 and the center of the absorbent sheet 18. Stored in the area. As a result, the urine amount can be accurately measured by the weighing scale 15.

  Here, as shown in FIG. 1, the mesh 22 of the present embodiment includes a plurality of slits 23. Various shapes are conceivable for the shape of the slit 23.

  For example, as shown in FIG. 8, the plurality of slits 23 may be formed of multiple radial slits 23 a to 23 d on a concentric circle. Among these radial slits 23a to 23d, in particular, the radial slits 23a and 23c formed in an odd-numbered ring shape counted from the outside and the radial slits 23b and 23d formed in an even-numbered ring shape counted from the outside. It is preferable that the slits do not exist on the same line in the radial direction, but are alternately arranged in a staggered manner. Thereby, for example, the urine flowing from the outer side of the outermost ring-shaped radial slit 23a does not fall in the outermost ring-shaped radial slit 23a. It falls at the radial slit 23b formed in a ring shape. Then, in the same manner, the urine which does not fall in the radial slit 23b falls in the next radial slit 23c formed in an inner ring shape, and further, the urine which does not fall in the radial slit 23c, It falls at the radial slit 23d formed in a ring shape.

  As a result, urine can be discharged near the center area of the absorbent sheet 18 in a nearly concentric state. This allows urine to be collected substantially uniformly around the measurement center without the urine being deviated and accumulated in any one direction of the absorption sheet 18, thereby reducing measurement errors.

  As described above, the pet toilet 1 of the present embodiment includes the support base 20 having the mesh 22 on the bottom surface 21 through which urine passes when the pet as an animal urinates, and the support base 20 has a lower side. An absorbing sheet 18 for absorbing urine is provided. A weighing scale 15 for measuring the urine absorbed by the absorbent sheet 18 is provided, and the mesh 22 is formed on the bottom surface 21 of the support base 20 so that the urine falls into the central region of the absorbent sheet 18. And a plurality of slits 23.

  As a result, urine falls only near the central region of the absorbent sheet 18 through the plurality of slits 23 formed on the bottom surface 21 of the support base 20.

  As a result, when urine is weighed by the weighing scale 15, the weight of the end of the absorbent sheet 18 does not become unbalanced and heavy, so that no fixed moment is generated and the measurement error does not increase.

  Therefore, when the urine absorbed by the absorbent sheet 18 is measured around the central area of the absorbent sheet 18 using the weighing scale 15, the measurement error is reduced even if the pet urinates at the end of the support base 20. It is possible to provide a pet toilet 1 that can be used.

  In the pet toilet 1 according to the present embodiment, the plurality of slits 23 are formed radially. As a result, urine can be discharged near the center area of the absorbent sheet 18 in a nearly concentric state.

  In the pet toilet 1 according to the present embodiment, the bottom surface 21 of the support base 20 is formed such that the plurality of slits 23 are at the lowest position. Accordingly, even when the pet urinates at a place different from the plurality of slits 23 on the support base 20, urine flows into the plurality of slits 23 due to the inclination. As a result, the urine can be reliably dropped on the absorbent sheet 18 through the plurality of slits 23 without retaining the urine on the bottom surface 21 of the support base 20. Therefore, a large amount of urination of the pet can be measured by the weighing scale, and the amount of urination of the pet can be accurately grasped.

  In the pet toilet 1 according to the present embodiment, the plurality of slits 23 are formed concentrically. As a result, urine can be discharged near the center area of the absorbent sheet 18 in a nearly concentric state.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. The configuration other than that described in the present embodiment is the same as that of the first embodiment. Further, for convenience of explanation, members having the same functions as the members shown in the drawings of Embodiment 1 are given the same reference numerals, and descriptions thereof are omitted.

  The pet toilet 2 of the present embodiment is different from the pet toilet 1 of the first embodiment in that ribs 24 are formed on a plurality of slits 23 as shown in FIG. ing.

  The configuration of the pet toilet 2 of the present embodiment will be described with reference to FIG. FIG. 9 is a plan view showing the configuration of the pet toilet 2 according to the present embodiment, and showing a radial slit 23 provided with a rib 24 formed on the support base 20 of the pet toilet 2.

  As shown in FIG. 9, the pet toilet 2 of the present embodiment has a plurality of radial slits 23 a to 23 d formed on the upper surface of the bottom surface 21 of the support base 20 and each of the radial slits 23 a to 23 d. Is formed with a rib 24. The plurality of ribs 24 are formed in a broken circle when viewed in plan.

  In particular, in the present embodiment, a plurality of concentric ribs 24a to 24d formed in concentric circles are formed on multiple radial slits 23a to 23d on the concentric circles, respectively. The concentric ribs 24a to 24d are, in particular, odd-numbered ring-shaped concentric ribs 24a and 24c counted from the outside and even-numbered ring-shaped circles formed from the outside. With the concentric ribs 24b and 24d, the solid lines of the dashed circles do not exist within the same center angle of the circle, but are staggered.

  Thus, for example, urine flowing from the outside of the outermost ring-shaped radial slit 23a is blocked by the outermost ring-shaped concentric rib 24a of a dashed circle, and the radial slit 23a Fall at. Then, the urine which does not fall in the radial slit 23a passes through the gap between the concentric ribs 24a of the dashed circle and reaches the next concentric rib 24b of the dashed circle formed in an inner ring shape. At that time, the urine flows along the circumference in the circumferential direction and drops at the radial slit 23b.

  Similarly, urine which does not fall in the radial slit 23b passes through the gap between the dashed circle concentric ribs 24b and reaches the next inner ring-shaped dashed circle concentric rib 24c. At that time, the urine flows along the circumference in the circumferential direction and drops at the radial slit 23c. Further, the urine that does not fall in the radial slit 23c passes through the gap between the dashed circle concentric ribs 24c and reaches the next inner ring-shaped dashed circle concentric rib 24d. At that time, the urine flows along the circumference in the circumferential direction and drops at the radial slit 23d.

  Therefore, urine is accumulated in a state of being diffused in the central region with respect to the absorbent sheet 18. As a result, the effect of dropping urine onto the absorbent sheet 18 in a state close to concentric without being biased in any direction can be further enhanced.

  As described above, in the pet toilet 2 of the present embodiment, the ribs 24 are formed on the upper surface of the bottom surface 21 of the support base 20, and the ribs 24 have a plurality of dashed circles in plan view. Have been.

  Accordingly, when the pet urinates at a place different from the plurality of slits 23 of the support base 20, the flow of urine can be guided by the ribs 24.

  In particular, in the pet toilet 2 of the present embodiment, when the rib 24 has a plurality of dashed circles formed concentrically in plan view, urine flowing into the outer dashed circle flows into the inner dashed circle. Are partially blocked and guided in the circumferential direction. As a result, the urine, which flows in from a plurality of slits 23 from the outside in the radial direction, is guided in the circumferential direction and is diffused in the circumferential direction.

  Therefore, urine can be discharged not only in the radial direction in the central region of the absorbent sheet 18 but also in such a manner that the urine is diffused in the circumferential direction from the radial direction.

  Therefore, even if the pet urinates at the end of the support base 20, the urine can be discharged to the central region of the absorbent sheet 18 and the effect of guiding the pet in a substantially concentric state in the central region can be improved.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIGS. The configuration other than what is described in the present embodiment is the same as that of the first and second embodiments. For convenience of explanation, members having the same functions as those shown in the drawings of the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

  In the pet toilet 3 of the present embodiment, in addition to the configuration of the pet toilet 1 of the first embodiment, one spiral recess 25 is formed on the bottom surface 21 of the support base 20 as shown in FIG. The difference is that they are formed.

  The configuration of the pet toilet 3 of the present embodiment will be described with reference to FIG. FIG. 10 shows a configuration of the pet toilet 3 in the present embodiment, and shows a radial slit provided with one spirally extending concave portion 25 formed on the bottom surface of the support base 20 in the pet toilet 3. It is a top view.

  In the pet toilet 3 of the present embodiment, as shown in FIG. 10, a plurality of radial slits 23 a to 23 d are formed on the upper surface of the bottom surface 21 of the support base 20, and the radial slits 23 a to 23 d A single spirally extending recess 25 is formed so as to extend over the entirety.

  Thus, the flow of urine can be guided along one spirally extending recess 25. Specifically, the urine flows as a vortex on the bottom surface 21 of the support base 20. As a result, urine is less likely to remain on the bottom surface 21 of the support base 20, and more urine is easily dropped from the slit 23.

  Note that the present invention is not limited to the above-described embodiment, and various changes can be made within the scope of the present invention.

  For example, in the pet toilet 3 of the above embodiment, one spirally extending recess 25 is formed on the plurality of slits 23 on the bottom surface 21 of the support base 20, but the spirally extending recess 25 is particularly The present invention is not limited to this. For example, as shown in FIG. 11, a pet toilet 4 in which a plurality of spirally extending recesses 26 are formed on a plurality of slits 23 in a bottom surface 21 of a support base 20. Is possible.

  That is, as shown in FIG. 11, the pet toilet 4 of the present embodiment has a plurality of concentric radial slits 23 a to 23 d formed on the upper surface of the bottom surface 21 of the support base 20 and a radial slit. Individual recesses 26a to 26g are formed as a plurality of spirally extending recesses 26 so as to extend over the entire slits 23a to 23d.

  Thereby, the flow of urine can be guided along the plurality of spirally extending concave portions 26. Specifically, the urine flows as a vortex on the bottom surface 21 of the support base 20. As a result, urine is less likely to remain on the bottom surface 21 of the support base 20, and more urine is easily dropped from the slit 23.

  In particular, when the concave portion 26 is composed of a plurality of individual concave portions 26a to 26g, since the outside of the vortex is open, even if the pet urinates to any end of the support base 20, the individual concave portion 26a At ~ 26 g, the flow of urine is directly guided to the slit 23, so that a large amount of urine easily falls into the slit 23.

  Thus, in the pet toilets 3 and 4 of the present embodiment, one or a plurality of spirally extending concave portions 25 and 26 are formed on the upper surface of the bottom surface 21 of the support base 20.

  Thus, when the animal urinates at a place different from the plurality of slits 23 of the support base 20, the flow of urine can be guided by the spirally extending concave portions 25 and 26. Specifically, the urine flows as a vortex on the bottom surface 21 of the support base 20. As a result, urine is less likely to remain on the bottom surface 21 of the support base 20, and more urine is easily dropped from the slit 23.

  In the above embodiments, the absorbent sheet 18 has been described as an example of a configuration for storing urine. However, the present invention is not limited to this. The excrement may be directly absorbed in the excretion tray 16 or the urine may be directly absorbed in the excretion tray 16.

[Summary]
The animal litter box (pet litters 1, 2, 3, 4) according to the first aspect of the present invention includes a support table 20 having a mesh 22 on a bottom surface 21 through which urine can pass when an animal urinates, and the support table. In an animal toilet provided with a holding body (absorbing sheet 18) for holding the urine below 20, a weighing scale 15 for measuring the urine absorbed in the holding body (absorbing sheet 18) is provided. In addition, the mesh 22 includes a plurality of slits 23 formed in the bottom surface 21 of the support base 20 so that the urine falls into a central region of the holding body (the absorbent sheet 18). And

  According to the above invention, the animal litter box includes a support having a mesh on the bottom surface through which urine passes when the animal urinates, and a holder for holding the urine is provided below the support. Have been. And in this invention, the weighing scale which weighs the urine held in the holding body is provided.

  In the animal litter box having the above configuration, when the mesh is provided on the entire bottom surface of the support, when the animal urinates at the end of the support, the urine falls through the mesh at the position to the end of the holder. I do. As a result, for example, when the urine held in the holder is weighed using a weighing scale with the center area of the holder as the measurement center, the weight of the end of the holder becomes unevenly heavier, so that it is fixed to the measurement center. A moment is generated and the measurement error increases.

  Therefore, in the present invention, the mesh is made up of a plurality of slits formed on the bottom surface of the support base so that urine falls into the central region of the holder. For this reason, the urine falls through only a plurality of slits formed on the bottom surface of the support base and only to the central region of the holder.

  As a result, when the weight is measured by the weighing scale, the weight of the end of the holder does not become unbalanced and heavier, so that no fixing moment is generated and the measurement error does not increase.

  Therefore, when measuring urine held in the holder with the central area of the holder as a measurement center using a weighing scale, an animal that can reduce measurement errors even if the animal urinates at the end of the support base. Toilets can be provided.

  An animal litter box (pet litter 1, 2, 3, 4) according to aspect 2 of the present invention is the animal litter box according to aspect 1, wherein the plurality of slits 23 are formed radially.

  As a result, urine is dispersed radially through the plurality of radial slits formed on the bottom surface of the support table and falls on the absorbent sheet.

  As a result, urine can be discharged in a state close to concentric with the central region of the holder. Therefore, the urine accumulates substantially uniformly around the measurement center without the urine being deviated and accumulated in any one direction of the absorbent sheet, thereby making it possible to reduce the measurement error.

  The animal litter box (pet litter 1) according to aspect 3 of the present invention is the animal litter box according to aspect 1 or 2, wherein the bottom surface 21 of the support base 20 is formed such that the plurality of slits 23 are at the lowest position. Have been.

  Thus, a plurality of slits for transmitting animal urine are formed on the bottom surface of the support base, and the plurality of slits are at the lowest position on the bottom surface of the support base. For this reason, even when the animal urinates at a place different from the plurality of slits on the support base, urine flows into the plurality of slits due to the inclination.

  As a result, even when the animal urinates at a place different from the plurality of slits on the support base, the urine can be reliably dropped on the holder through the plurality of slits without retaining the urine on the bottom surface of the support base. .

  Therefore, much of the urine output of the animal can be measured by the weight scale, and the urine output of the animal can be accurately grasped.

  An animal litter box (pet litter 1, 2, 3, 4) according to aspect 4 of the present invention is the animal litter box according to any one of aspects 1 to 3, wherein the plurality of slits 23 are formed concentrically. I have.

  Thereby, since a plurality of slits are formed concentrically in a multiplex manner, urine can be discharged so as to reach the central region of the holder.

  The animal litter box (pet litter 2) according to aspect 5 of the present invention is the animal litter box according to aspect 4, wherein a rib 24 is formed on the upper surface of the bottom surface 21 of the support base 20, and the rib 24 Are formed in a broken line circle shape in plan view. The fact that the rib is formed in the shape of a broken line circle in a plan view means that the rib has a shape of a circle having a cut as shown in a broken line circle in a plan view. In other words, it means that the ribs formed of the standing walls are circularly formed in a plan view and are provided discretely at regular intervals.

  Thereby, when the animal urinates at a place different from the plurality of slits of the support base, the flow of urine can be guided by the rib.

  Here, in the present invention, in particular, since a plurality of ribs are formed in a dashed circle in plan view, urine flowing into the outer dashed circle is partially blocked by the inner dashed circle. , Are guided in the circumferential direction. As a result, the urine flowing from the outside in the radial direction is guided in the circumferential direction in the plurality of slits, so that the urine is diffused in the circumferential direction.

  Therefore, urine can be discharged not only in the radial direction in the central region of the holder but also in such a manner as to be diffused in the circumferential direction from the radial direction.

  The animal litter box (pet litters 3.4) according to the sixth aspect of the present invention is the animal litter box according to the fourth aspect, wherein one or a plurality of spirally extending concave portions are formed on the bottom surface 21 of the support base 20. I have.

  Thus, when the animal urinates at a place different from the plurality of slits of the support base, the flow of urine can be guided by the spirally extending recess. Specifically, urine flows as a vortex on the bottom surface of the support base. As a result, urine is less likely to remain on the bottom surface of the support table, and more urine is easily dropped from the slit.

  Here, in particular, when the concave portion is formed to extend in a plurality of spirals, the outside of the vortex is open, so that even if the animal urinates at any end of the support table, the urine remains in the concave portion. The flow of water is directly led to the slit, so that a large amount of urine easily falls into the slit.
