<1. First Embodiment>
FIG. 1 is a cross-sectional view of an animal toilet 100 according to the first embodiment. FIG. 2 is an exploded perspective view showing the interior of the animal toilet 100. The animal toilet 100 is an excrement collection apparatus that receives and collects excrement discharged while the animal P is on the upper part by the diffusion unit 31. The animal toilet 100 includes a housing 11, a ceiling plate 21, a diffusion unit 31, a cleaning liquid supply unit 41, a collection device 51, a suction pump 61, and a sensor 71.

  The housing 11 is a housing that opens upward and houses the diffusion portion 31 and the recovery device 51 therein. A ceiling plate 21 is attached to the opening at the top of the housing 11, and the opening at the top is partially blocked by the ceiling plate 21.

  The ceiling board 21 is a metal mesh board, and a large number of gaps (through holes H1) are formed. By providing the through hole H1, the ceiling plate 21 can pass the discharged urine, a certain amount of feces, and the like downward. The end portion of the ceiling plate 21 is supported by the housing 11 and is disposed on the uppermost part of the animal toilet 100.

  In addition, when the height of the ceiling board 21 is higher than the ground, the animal P can access the ceiling board 21 by bridging the slope board over the ceiling board 21. In addition, the ceiling board 21 may be adjusted to the height above the ground by burying the animal toilet 100 in the ground. In this case, access means such as a slope plate can be omitted.

  The diffusing unit 31 is arranged to be spaced downward from the ceiling plate 21. The diffusion part 31 has a receiving surface S1 for receiving excrement so that the height gradually decreases from the apex T1 having the highest height in the central part toward the peripheral terminal part. The diffusion unit 31 has a function of diffusing excrement that has passed through the ceiling plate 21 to the surroundings. In this embodiment, the diffusion part 31 is formed in a dome shape. That is, as the receiving surface S1 moves toward the end portion, the curved surface changes so that the gradient becomes steep.

  Note that the fact that the height of the receiving surface S1 gradually decreases means that the height changes constantly. Therefore, for example, a portion where the height changes discontinuously by being formed in a step shape may be provided in the middle of the receiving surface S1. By forming the receiving surface S <b> 1 so that the height is always lower toward the periphery, excrement discharged to the diffusing portion 31 is easily moved downward.

  The cleaning liquid supply unit 41 has a function of supplying tap water, an aqueous solution containing a detergent, an aqueous solution having an effect of deodorizing ammonia odor, and the like (hereinafter referred to as a cleaning liquid) to the apex T1 of the diffusion unit 31. The cleaning liquid supply unit 41 includes a water tank 42 incorporating a pump and the like, a cleaning liquid discharge unit 43 installed at the apex T1 on the surface of the receiving surface S1 of the diffusion unit 31, and a space between the water tank 42 and the cleaning liquid discharge unit 43. And a cleaning liquid supply pipe 44 to be connected.

  The water tank 42 is provided outside the housing 11 as shown in FIG. The cleaning liquid supply pipe 44 passes through the outer wall portion of the housing 11 and extends to the apex portion T1 of the diffusion portion 31 accommodated in the housing 11. The water tank 42 is appropriately supplemented with a cleaning liquid.

  As shown by a thick arrow in FIG. 2, a discharge port is formed in the cleaning liquid discharge portion 43 so as to discharge the cleaning liquid around. The cleaning liquid discharge unit 43 may be configured to discharge the cleaning liquid from a slit-shaped discharge port that opens at the entire outer peripheral portion, or may discharge the cleaning liquid in one or more predetermined directions. The cleaning liquid may be discharged to the periphery by rotating the outlet around a predetermined axis. Furthermore, the cleaning liquid discharge unit may be configured such that the cleaning liquid discharged from the opening in one or more predetermined directions flows down while drawing a vortex.

  By providing the cleaning liquid discharge part 43 at the apex T1, the receiving surface S1 of the diffusion part 21 can be efficiently cleaned with a relatively small amount of cleaning liquid.

  The recovery device 51 has an inner surface S2 that gradually decreases in height from the periphery toward the bottom B1 inside the center. The inner side surface S <b> 2 of the recovery device 51 extends farther outward than the end portion of the diffusion portion 31. The collection device 51 receives and collects excrement, which is diffused around by the diffusion portion 31 and falls downward from the peripheral end portion, on the inner surface S2. In the present embodiment, the recovery device 51 has a bowl-shaped (bowl-shaped) inner side surface S2 whose slope becomes gentler toward the bottom B1 at the center.

  A recovery hole H2 is provided in the bottom B1 of the recovery device 51. A conduit 52 connected to the suction pump 61 is connected to the recovery hole H2. The suction pump 61 sucks and collects excrement and cleaning liquid collected at the bottom B1 of the collecting device 51 through the conduit 52. The excrement collected by the suction pump 61 is appropriately discarded.

  Further, a sensor 71 for detecting liquid is attached in the vicinity of the recovery hole H2 in the inner side surface S2. The sensor 71 has a function of detecting a liquid material such as urine.

  The sensor 71 may be of a type that detects an electric resistance value that changes in accordance with the presence or absence of a liquid, or a type that optically detects the presence or absence of a liquid using a laser beam or the like. However, the sensor 71 may be any sensor as long as it can detect excrement, and may be configured to detect a change in weight, for example.

  FIG. 3 is a block diagram illustrating the connection between the sensor 71 and the cleaning liquid supply unit 41 and the connection between the sensor 71 and the suction pump 61. As shown in FIG. 3, in this embodiment, when the sensor 71 detects a liquid, the sensor 71 outputs a detection signal to the cleaning liquid supply unit 41 and the suction pump 61. The cleaning liquid supply unit 41 that has received the detection signal drives the pump built in the water tank 42 to discharge the cleaning liquid from the cleaning liquid discharge unit 43 for a predetermined time. In addition, the suction pump 61 that has received the detection signal starts the suction operation. The suction pump 61 is configured to perform a suction operation for a period longer than the predetermined time in order to collect not only the excrement but also the cleaning liquid discharged from the cleaning liquid discharge unit 43.

  In this manner, by operating the cleaning liquid supply unit 41 and the suction pump according to the detection of the liquid by the sensor 71, when the excrement is discharged to the animal toilet 100, the cleaning of the animal toilet 100 and the excretion of the excrement are performed. Recovery can be performed automatically.

  As shown in FIGS. 1 and 2, the sensor 71 is provided in the vicinity of the lowest recovery hole H <b> 2 on the inner surface S <b> 2 of the recovery device 51. Thereby, the sensor 71 can detect in the part where excrement, such as urine, collects. Therefore, even when the detection range of the sensor 71 is small, the liquid in the excrement in the animal toilet 100 can be appropriately detected.

  In the present embodiment, the lowest portion of the inner surface S2 of the recovery device 51 is set at the center, but may be set outside the center. However, by setting the lower portion at the center of the collecting device 51 instead of the outside, it is possible to give a larger gradient to the inner side surface S2 while suppressing an increase in the height dimension of the collecting device 51. . That is, the excrement easily moves downward without unnecessarily enlarging the collection device 51.

  As described above, according to the animal toilet 100 of the present embodiment, by providing the dome-shaped diffusion part 31 that is a receiving part of excrement, the cleaning liquid is caused to flow from the apex T1 of the diffusion part 31 to the surroundings. The entire receiving surface S1 can be cleaned evenly. Therefore, the animal toilet 100 can be easily washed.
