In the present embodiment, the central side of the flat portion 32 is formed in a mesh shape, and the passage holes 31 have a square shape in a planar view, and are arranged side by side in front, rear, left, and right. The lower protruding portion 33 is formed over the entire circumference of the flat portion 32 and contacts the top surface of the groove 4 .

The tank 4 is made of, for example, plastic, and collects urine passing through the passage hole 31 of the foothold member 3 . As shown in FIGS. 4 and 5 , the groove 4 is formed in a substantially cuboid shape having four side walls, a bottom wall, and an upper wall. Specifically, the tank 4 has a front wall 41 , a right side wall 42 , a rear wall 43 , and a left side wall 44 as four side walls, a bottom wall 45 , and an upper wall 46 . In this embodiment, the front wall 41, the right side wall 42, the rear wall 43, the left side wall 44 and the bottom wall 45 constitute a recess capable of storing liquid, and the upper wall 46 constitutes a plate-shaped plugging portion that blocks the opening of the recess.

The upper wall 46 is formed with a recovery hole 4a that receives urine passing through the passing hole 31 of the foothold member 3 on the top surface, and allows the urine to flow into the tank 4 . As shown in FIG. 4 , the recovery hole 4 a is arranged offset from the center of the upper wall 46 along the front-rear direction and the left-right direction, and is formed in a rectangular shape in plan view. Furthermore, in the present embodiment, the upper wall 46 is formed to incline so as to descend from the outer edge toward the center. That is, the top surface of the upper wall 46 extends from below the passing hole 31 across the recovery hole 4a, and descends and inclines toward the recovery hole 4a.

And, as shown in Figure 2, the tank 4 has: a grip portion 4b for the operator to hold; a maintenance hole 4c that is formed separately from the recovery hole 4a to discharge the liquid inside; The cover 49 of the opening and closing part freely. In the present embodiment, the grip portion 4b is disposed on the center side of the front wall 41 in the horizontal direction. The maintenance hole 4c is arranged on the right end side of the groove along the extending direction (left-right direction) of the front wall 41 on which the grip portion 4b is arranged, and is arranged on the front side. In the present embodiment, an inclined surface 48 having corners of a cuboid is formed at the meeting portion of the front wall 41 and the right side wall 42 in the tank 4 , and the maintenance hole 4c is arranged on the inclined surface 48 .

Furthermore, as shown in FIG. 4 , the tank 4 has a scattering preventing portion 47 for preventing the liquid in the tank 4 from scattering. The scattering preventing part 47 includes: a substantially horizontal plate-shaped preventing part body 47a overlapping with the recovery hole 4a in plan view; extending upward from the peripheral edge of the preventing part body 47a on the opposite side to the maintenance hole 4c along the left-right direction. Connected with the upper wall 46, surround the surrounding walls 47b, 47c above the prevention part body 47a from the opposite side to the maintenance hole 4c; formed between the circumferential ends of the surrounding walls 47b, 47c, along the left and right direction, from preventing An opening 47d extending upward from the peripheral edge of the maintenance hole 4c side of the main body. In this embodiment, the surrounding walls 47b, 47c are composed of the following: extending upward from the left end of the preventing part body 47a and connecting the left surrounding wall 47b with the upper wall 46; The upper wall 46 connects the front and rear pair of front and rear surrounding walls 47c. That is, as shown in FIG. 5 , each front and rear surrounding wall 47c surrounds the grip portion 4b side (front side) and the side opposite to the grip portion 4b (rear side) above the prevention portion main body 47a along the front-rear direction. And, as shown in FIG. 7, the groove 4 has: a flange portion 47e extending downward from the lower side of the opening 47d in the periphery of the prevention portion body 47a; extending downward from the upper wall 46, and the lower end constitutes one of the upper ends of the opening 47d. Limiting wall 47f. The flange portion 47e prevents the liquid scattered around the prevention portion main body 47a from entering the recovery hole 4a side, and the restriction wall 47f also suppresses the liquid from entering the recovery hole 4a side by narrowing the opening 47d.

As shown in FIG. 6, the grip portion 4b is composed of the following: a recess 4b1 formed by recessing the front wall 41 toward the rear; a front wall 4b2 extending downward from the front end of the upper wall 46; a barb portion 4b3 extending backward from the front wall 4b2 . In this embodiment, the recessed part 4b1 is formed in the front wall 41 over the upper and lower sides. And the front wall 4b2 and the recessed part 4b1 are formed in front and behind with a space|interval.

As shown in FIG. 4 , the recovery hole 4 a is formed on the side of the grip portion 4 b from the center of the upper wall 46 along the direction (front-rear direction) perpendicular to the direction in which the front wall 41 on which the grip portion 4 b is disposed is extended. (front side). Further, the recovery hole 4a is formed on the opposite side (left side) from the center of the upper wall 46 to the maintenance hole 4c along the extending direction (left-right direction) of the front wall 41 provided with the grip portion 4b.

In this embodiment, the position of the recovery hole 4a is set in consideration of the following: the holding posture of the state in which the tank 4 is held; the discharge posture of the state in which the liquid in the tank 4 is discharged; and the right side wall 42 in the tank 4 It is a loading posture facing down and placed in a specified place. As shown in FIG. 7 , the capacity at which the liquid in the tank 4 becomes the water level L1 corresponding to the bottom surface of the prevention portion main body 47 a is taken as a reference capacity. Again as shown in Figure 8, set the position of recovery hole 4a, when making the front wall 41 that is equipped with grip portion 4b with groove 4 become the grip posture of top, the liquid of the reference volume in groove 4 The water level L2 is lower than the recovery hole 4a. Furthermore, the position of the recovery hole 4a is set so that when the tank 4 is tilted downward from the holding posture to the side of the maintenance hole 4c, the water level L3 of the liquid of the reference capacity reaches the discharge posture of the maintenance hole 4c, The water level L3 of the liquid of the reference capacity in the tank 4 is lower than the recovery hole 4a. Furthermore, the position of the recovery hole 4a is set so that the water level L3 of the liquid of the reference capacity in the tank 4 is higher than that of the recovery hole when the tank 4 is placed in a mounting posture in which the right side wall 42 faces downward and is placed at a predetermined place. 4a is still low.

Furthermore, as shown in FIG. 7 , the tank 4 has a urine treatment liquid 6 stored inside for treating urine. The urine treatment solution 6 uses water as a solvent, and an acid that reacts with ammonia and a surfactant that kills microorganisms as a solute. In this embodiment, tartaric acid is used as the acid of the urine treatment solution 6 , and benzalkonium chloride is used as the surfactant of the urine treatment solution 6 . The capacity of the tank 4 is arbitrary, but for example, the aforementioned reference capacity can be 5 liters or more and 20 liters or less. By accumulating more than 5 liters of liquid in the tank 4, it can correspond to the urine of small dogs for about one week, and by keeping the capacity of the tank 4 below 20 liters, the tank 4 can be made compact and a pet toilet can be obtained 1 miniaturization.

According to the pet toilet 1 configured as above, when the pet defecates on the foothold member 3 , the discharged urine falls below the foothold member 3 through the passage holes 31 . The urine falling below the foothold member 3 is received by the top surface of the upper wall 46 of the tank 4, then guided to the recovery hole 4a along the slope of the top surface, and flows into the tank 4 from the recovery hole 4a. The urine flowing into the tank 4 is treated with the urine treatment liquid 6 and stored in the tank 4 .

In the present embodiment, ammonia contained in urine is neutralized by tartaric acid contained in the urine treatment solution 6 to form ammonium tartrate. According to this, the ammonia contained in the urine disappears immediately after the urine flows into the tank 4 , and the tank 4 is prevented from being filled with unpleasant odors due to ammonia. In addition, the microorganisms contained in the urine are killed by the benzalkonium chloride contained in the urine treatment solution 6 . Accordingly, the urea contained in the urine is not decomposed into ammonia by microorganisms, and the generation of ammonia in the tank 4 can be suppressed. In addition, components other than urea contained in urine are not decomposed by microorganisms. Therefore, even if urine accumulates in the tank 4 for a long period of time, urea and other components will not be decomposed to generate unpleasant odors.

Here, the concentrations of tartaric acid and benzalkonium chloride in the urine treatment solution 6 are initially accumulated in the tank 4, consumed, diluted, and reduced as urine flows into the tank 4. Although the concentrations of tartaric acid and benzalkonium chloride in the urine treatment liquid 6 are arbitrary, they need to be set so that the urine flows into the tank 4 and when the liquid in the tank 4 reaches the aforementioned reference volume, the effect of treating urine is maintained. For example, if tartaric acid can be kept at 0.05% by weight or more and benzalkonium chloride can be kept at 0.05% by weight or more, the effect of treating urine can be maintained. Therefore, it is preferable to determine the amount of the urine treatment liquid 6 initially stored in the tank 4 in consideration of the consumption of tartaric acid and benzalkonium chloride and the degree of dilution until the standard capacity is reached. For example, the concentrations of tartaric acid and benzalkonium chloride in the initial urine treatment liquid 6 may be not less than 2.0% by weight and not more than 10.0% by weight. Furthermore, for example, the amount of the initial urine treatment liquid 6 can be 50 cc to 1000 cc. By keeping the concentration of benzalkonium chloride below 10.0% by weight, it can be made relatively safe to the human body. Furthermore, when the density|concentration of tartaric acid is 10.0 weight% or less, the odor of tartaric acid can be suppressed to the level which the people around a toilet do not notice.

In this way, since the urine discharged from the pet is recovered to the tank 4 and treated with the urine treatment liquid 6, unless all the urine treatment liquid 6 in the tank 4 is consumed, no odor due to urine will be generated. Therefore, there is no need to maintain a state where the foothold member 3 is covered with toilet sand to prevent odor as in the past, and the monitoring burden of the pet toilet 1 for the breeder can be reduced. Moreover, once the urine treatment liquid 6 is replenished in the tank 4, the pet's urine can be treated for a long time. Therefore, it is not necessary to replace the toilet litter regularly as in the past, and it can be left for a long time, allowing the breeder to relieve stress. Moreover, there is no need to cover the toilet sand on the foothold member 3 as in the past, the toilet sand can be saved, and only the portion of the toilet sand can reduce the height direction dimension of the pet toilet 1, and the small size of the pet toilet 1 can be achieved. change.

Furthermore, since the urine treatment liquid 6 is a liquid, the surfactant and the acid in the urine treatment liquid 6 can be consumed uniformly and reliably. On the other hand, in the configuration in which the solid urine treatment material is put into the tank 4, the urine treatment material 10 near the inflow part is consumed first, and unevenness occurs in the consumed state of the urine treatment material in the tank 4, which cannot be stabilized. Exhibits deodorizing performance. Furthermore, in the configuration of putting the solid urine treatment material into the tank 4, if the content of surfactant and acid in the urine treatment material is increased, so that the urine treatment function will not be damaged for a long time, it will be difficult for the first use. The last small amount of urine will dissolve the excess surfactant and acid. Accordingly, the concentration of the surfactant and the acid in the liquid in the tank 4 becomes extremely high, and there is a possibility of adverse effects on the human body during the discharge operation of the liquid, which is very dangerous. In the pet toilet 1 of the present embodiment, since the surfactant and the acid are consumed along with the treatment of urine, the concentration of the surfactant and the acid in the urine treatment solution decreases with time. Therefore, if the concentration of the surfactant and the acid in the urine treatment liquid 6 at the beginning of use is at a concentration safe to the human body, then the concentration will not be exceeded during use, and there is no need to administer the acid to the human body during the discharge operation of the liquid in the tank 4. risk of adverse effects.

Furthermore, since the groove 4 where the liquid is stored is blocked by the upper wall 46, the urine treatment liquid 6 accumulated in the groove 4 does not scatter around. In particular, according to this embodiment, even if vibration is applied to the tank 4 or the tank 4 is inclined by moving the pet toilet 1, etc., the scattering prevention part 47 arranged in the tank 4 prevents the liquid in the tank 4 from being scattered to the recovery area. outside of hole 4a.

Furthermore, the user of the pet toilet 1 can discharge the treated urine through the maintenance hole 4c by removing the cover 49 and opening the maintenance hole 4c. When discharging urine, the operator first takes the front wall 21 into the open state as shown in FIG. Then, the tank 4 is held by the holding portion 4b, and the tank 4 is transported to a place where urine can be discharged, such as a toilet in a house. At this time, the posture of the tank 4 changes from the basic posture in which the upper wall 46 is upward to the holding posture in which the front wall 41 is upward, and accordingly, the liquid in the tank 4 also mainly moves from the bottom wall 45 side to the rear wall 43 side. . Although the liquid in the tank 4 moves relative to the recovery hole 4a mainly in the front-back direction and the up-down direction, because the prevention part body 47a is located directly below the recovery hole 4a, the front and back of the top of the prevention part body 47a are surrounded by the front and rear walls 47c. Covering, it can definitely prevent the liquid from scattering to the side of the recovery hole 4a. Furthermore, because in the holding posture, the water level L2 of the reference volume of liquid in the tank 4 is lower than the recovery hole 4a, so the urine in the tank 4 will not flow out through the recovery hole 4a when the tank 4 is transported.

And because the side of the maintenance hole 4c is inclined downward from the holding posture, the water level L3 of the liquid of the reference capacity in the tank 4 is lower than that of the recovery hole 4a under the discharge posture in which the water level L3 of the liquid of the reference capacity reaches the maintenance hole 4c. Therefore, when urine is discharged, the urine in the tank 4 does not flow out to the outside through the recovery hole 4a. Furthermore, even when the tank 4 is placed in a mounting posture with the right side wall 42 facing downward and the tank 4 is placed at a predetermined position, the water level L3 of the liquid of the reference capacity in the tank 4 is lower than the recovery hole 4a. , so the urine in the tank 4 will not flow out to the outside through the recovery hole 4a. Accordingly, for example, even when the operator places the tank 4 and temporarily places it in a predetermined place before the urine discharge operation, the urine in the tank 4 does not flow out to the outside through the recovery hole 4a. Moreover, even if the urine in the tank 4 enters the prevention part main body 47a from the opening 4d due to the vibration or the like when the operator places the tank 4 at a predetermined position, the opening 4d is formed on the side of the maintenance hole 4c. Urine on the preventer body 47a quickly falls into the tank 4 through the opening 4d.

In addition, although tartaric acid was used as the acid which reacts with the ammonia of the urine treatment liquid 6 in the said embodiment, it is also possible to use other acids, such as citric acid. Also, although the use of benzalkonium chloride as the surfactant for killing microorganisms in the urine treatment solution 6 was shown, other surfactants such as quaternary ammonium salt may also be used. In addition, although it was shown that the urine treatment liquid 6 contains both an acid and a surfactant, either one may be included. In addition, as the urine treatment liquid 6, a liquid containing aroma components other than an acid and a surfactant may be used.

In addition, the pet toilet 1 of the above-mentioned embodiment may be provided with notification means for notifying the breeder or the like that the liquid in the tank 4 has reached the above-mentioned reference capacity. For example, the notification means is constituted as follows: a float (floater) arranged in the tank 4 that moves up and down according to the water level of the liquid; At the same time, the top of the float is colored into a color different from that of the groove 4. When the liquid in the groove 4 reaches the water level L1 consistent with the bottom surface of the prevention part body 47a, the top of the float is also in contact with the upper wall 46. For example, the float has: a body whose upper part is made of a color different from that of the groove 4; and an engaging part provided on the body and the column. In this case, by floating the color of the upper part of the float on the upper wall 46 of the tank 4, breeders and the like can know that the liquid in the tank 4 has reached the aforementioned reference capacity. Here, the installation positions of the floats and columns are arbitrary, but in consideration of the visibility of the color of the floats from the outside, it is preferable to install them near the center of the tank 4 along the front-rear direction and the left-right direction. Furthermore, the rigidity and strength of the tank 4 can be effectively improved by disposing the column at the center in planar view.

Moreover, in the foregoing embodiment, although the groove 4 has been shown to be formed in a substantially rectangular parallelepiped shape, if it is equipped with: a concave portion that can store liquid, and a gap between the opening of the concave portion and the urine that passes through the passage hole of the foot member on the top surface. The shape of the plate-shaped plugging portion can be changed as appropriate. Furthermore, the specific configurations of the grip portion 4b, the maintenance hole 4c, and the scattering prevention portion 47 of the tank 4 can also be changed arbitrarily, and some or all of them can be omitted.

Furthermore, as shown in FIG. 13 , the tank 104 has the urine treatment liquid 6 stored inside for treating urine. The urine treatment solution 6 uses water as a solvent, and an acid that reacts with ammonia and a surfactant that kills microorganisms as a solute. Also in this embodiment, tartaric acid is used as the acid of the urine treatment solution 6 , and benzalkonium chloride is used as the surfactant of the urine treatment solution 6 . The capacity of the tank 104 is arbitrary, but can be, for example, not less than 5 liters and not more than 20 liters. By accumulating more than 5 liters of liquid in the tank 104, it can correspond to about one week's urine of small dogs, and by keeping the tank 104 dense and smaller than 20 liters, the pet toilet 101 can be miniaturized.

As shown in FIG. 9 , the cover 5 is formed to cover one long side of the rectangular footing point member 103 in plan view. The vertical length of the cover 5 is a dimension that adds up the long side and the short side of the foothold member 103, and a plurality of creases 5a that are selectively bendable are formed at arbitrary positions in the longitudinal direction. In the present embodiment, creases 5 a are formed at half lengths of the short sides of the foothold member 103 from both ends in the longitudinal direction, and at positions of the length of the short sides of the foothold member 103 . Accordingly, the cover 5 can take the form of covering one long side of the foothold member 103 and half of the short sides of both sides as shown in FIG. The shape of the long side and the short side of one side. The cover 5 is selectively mounted on the foot point member 103, like a male dog, suitable for use with respect to pets that raise their feet when defecating.

According to the pet toilet 101 constituted as above, since the urine discharged by the pet is recovered to the tank 104 and processed by the urine treatment liquid 6, unless all the urine treatment liquid 6 in the tank 104 is consumed, otherwise there will be no The smell of urine. Therefore, it is not necessary to maintain a state where the foothold member 103 is covered with toilet sand in order to prevent odor as in the past, and the monitoring burden of the pet toilet 101 for the breeder can be reduced. Furthermore, once the urine treatment solution 6 is first replenished in the tank 104, the pet's urine can be treated for a long period of time. Therefore, it is not necessary to replace the toilet litter regularly as in the past, and it can be left for a long time, allowing the breeder to relieve stress. Moreover, there is no need to cover the toilet sand on the foothold member 103 as in the past, the toilet sand can be saved, only the portion of the toilet sand can reduce the height direction dimension of the pet toilet 101, and the small size of the pet toilet 101 can be achieved. change.

Also in the present embodiment, ammonia contained in urine is neutralized by tartaric acid contained in the urine treatment liquid 6 to form ammonium tartrate. According to this, the ammonia contained in the urine disappears immediately after the urine flows into the tank 104 , and the tank 104 is not filled with a bad smell due to ammonia. In addition, the microorganisms contained in the urine are killed by the benzalkonium chloride contained in the urine treatment solution 6 . Accordingly, urea contained in urine is not decomposed into ammonia by microorganisms, and the production of ammonia in the tank 104 can be suppressed. In addition, components other than urea contained in urine are not decomposed by microorganisms. Therefore, even if the liquid to be treated is stored in the tank 104 for a long period of time, urea and other components will not be decomposed to generate unpleasant odors.

Furthermore, since the recessed portion of the groove 104 for storing liquid is blocked by the upper wall 146, the liquid accumulated in the groove 104 does not scatter to the surroundings. In particular, according to this embodiment, even if vibration is applied to the tank 104 or the tank 104 is inclined by moving the pet toilet 101, etc., the scattering prevention part 147 arranged in the tank 104 prevents the liquid in the tank 104 from being scattered to the recovery area. outside of hole 104a.

Also, the user of the pet toilet 101 can discharge the accumulated liquid through the maintenance hole 104c by removing the cover 149 and opening the maintenance hole 104c. As shown in FIG. 10 , the maintenance work by the user can be carried out by taking the front wall 121 into the open state, sliding the groove 104 to the front, and taking out the groove 104 . In this embodiment, since the urine treatment liquid 6 does not contain harmful components, the user can simply and easily discard the urine treated by the urine treatment liquid 6 . In addition, the replenishment of the urine treatment liquid 6 may be performed from either the recovery hole 104a or the maintenance hole 104c.

In addition, in the above-mentioned embodiment, although the scattering prevention part 147 of the tank 104 was shown as being connected to the upper wall 146, it may be connected to the front wall 41, the left side wall 44, the rear wall 43, or the right side wall 42, for example. In addition, although the scattering prevention part 147 is shown as having the first connection wall 147b, each second connection wall 147c, and the flange part 147d, if it has a part overlapping the recovery hole 104a in plan view, the shape etc. can be changed arbitrarily. In addition, the structure which omits the scattering prevention part 147 is also possible.
