- the toilet since a plurality of holes 12a are formed in the urine passage portion 100 of the upper container 10 of the animal toilet 1, the toilet is formed from the holes 12a of the urine passage portion 100 via the fan 52 and the discharge port 51a. There is a flow of air to the outside of the toilet. Therefore, the bad odor of the urine passing portion 100 (the stool odor above the urine passing portion 100 and the urine odor rising from the absorber 20a) can be induced downward, and the bad odor can be induced without covering the animal toilet 1. Can prevent the spread of urine.
- a gap G is formed between the edge of the detachable opening 33a of the front wall portion 33 of the lower container 30 and the tray 20.

- the animal toilet 1'of the third embodiment is a toilet having a different form from the animal toilet 1 of the above-described embodiment (the position of the urine passage portion and the absorber is eccentric from the center).
- the front-rear direction is the direction along the short side of the animal toilet 1'
- the left-right direction is the direction along the longitudinal direction of the animal toilet 1'.
- "front”, “rear”, “right”, “left”, “top”, and “bottom” are defined for each direction (front-back direction, left-right direction, up-down direction).
- front-back direction left-right direction, up-down direction
- the side where the tray 20'is pulled out from the lower container 30' in the front-rear direction is defined as "front”.
- the animal toilet 1 ′ includes an upper container 10 ′, a lower container 30 ′, a tray 20 ′ housed in the lower container 30 ′, and a cover 40 ′. Further, the animal toilet 1'is provided with a ventilation device 50.
- the upper container 10'of the third embodiment is a box-shaped member having an open upper portion, has a rectangular shape as shown in FIG. 13 when viewed from above, and has a length in the left-right direction in the front-rear direction. It is longer than the length in. That is, the long side of the rectangle is formed along the left-right direction, and the short side of the rectangle is formed along the front-back direction. Further, the upper container 10'is provided with a urine passage portion 100' eccentrically to the right side of the center in the left-right direction. The configuration of the urine passage portion 100'is substantially the same as that of the urine passage portion 100 of the above-described embodiment. However, the urine passage portion 100'of the third embodiment has a long slit shape in the left-right direction (see FIG. 14). Further, although not shown, the excrement treatment agent S is installed on the urine passage portion 100'as in the above-described embodiment.
- the tray 20' is a flat box-shaped container with a shallow bottom in which an absorber 20a that absorbs excreted urine or the like is placed.

That is, the ventilation device 50 includes a fan 52, a filter group 53, and the like. Further, the ventilation device 50 is provided in the lower container 30', and exhausts (exhausts) the air in the animal toilet 1'(lower container 30') to the outside. Thereby, the bad odor can be efficiently removed.
- the location of the ventilation device 50 may be any of R1 to R11 shown in FIG. 14, but it is preferably other than R2 and R9 (R2 and R9 may interfere with the handle). For). More preferably, other than R7, R8, R10 and R11 is preferable (because R7, R8, R10 and R11 are far from the absorber 20a and the urine passage portion 100'). More preferably, R4, R5 and R6 are preferable, and most preferable are R1 and R3 (the present embodiment). In R1 and R3, since the fan 52 is close to the absorber 20a and the fan 52 can be arranged diagonally with respect to the absorber 20a, the ventilation efficiency can be improved. Further, the ventilation device 50 may be provided at a plurality of locations (for example, R1 and R3) among R1 to R11 shown in FIG.

- the gap G is formed on the front side of the lower container 30, air easily flows from the gap G to the fan 52. Therefore, the air flow can be improved. Further, when the air flow is improved, the moist absorber 20a and the excrement treatment material S can be dried, so that the humidity can be lowered and the generation of bacteria that are the basis of the odor can be suppressed. In addition, the absorption capacity of the absorber 20a can be restored by the evaporation of urine accumulated in the absorber 20a. Further, since the stool in the upper layer (upper container 10) and the excrement treatment material S to which the stool is attached dries, it is easy to remove the odor group.
- three filters (deodorant filter 53a, sand prevention filter 53b, water repellent filter 53c) of the filter group 53 of the ventilation device 50 are provided inside the fan 52.
- the deodorizing filter 53a may be arranged outside the fan 52 (rear side in the case of FIG. 7). Even in this case, the malodorous component of the animal toilet 1 can be adsorbed on the deodorizing filter 53a, and the malodor can be prevented from diffusing to the outside (living space).
