The upper output part 61 has a tray contact part 61a with which the tray 30 abuts, and at least one or more upper load cells (not shown) that are output parts inside the upper output part 61. The tray contact portion 61a is a flat surface over the entire surface of the upper output portion 61. The lower output unit 62 includes a lower load cell 63 that is an output unit and a control unit (not shown). The lower load cells 63 are provided at the four corners of the bottom surface of the lower output portion 62, project downward, and are also legs that support the entire animal litter box 1. The upper load cell and the lower load cell 63 are columnar compression type sensors that convert the applied force into an electric signal and output the electric signal.

The control unit is connected to the upper load cell and the lower load cell 63 by a wired or wireless signal line, and receives a signal output from each load cell. The control unit has a communication unit (not shown), a storage unit (not shown), and a processing unit (not shown). The communication unit is a unit that performs wireless communication with terminals such as a load cell, a smartphone, and a tablet terminal. The storage unit includes a RAM, a ROM, and the like, and is a unit that stores various data and programs. For example, it is possible to store the detected weight before excretion, the weight of excrement, the number of excretion, the correction value associated with the excrement disposal agent, and the like. The processing unit includes a CPU and the like, and is a unit that performs various calculations. For example, calculation processing such as calculating the weight of excrement from each detection result such as the weight before excretion and the weight after excretion stored in the storage unit is performed.

<< Operation of excrement weight measurement by the animal litter box 1 >>
FIG. 11 is a schematic view of a cross section taken along the line AA in FIG. In FIG. 11, the upper container 10 and the cover 50 are omitted. As described above, the supported portion 32 of the tray 30 is supported by the support portion 41 of the support container 40 in the tray 30 that is pulled out from the support container 40 from the main body portion 20. On the other hand, when the tray 30 is in use, the bottom surface of the tray 30 comes into contact with the upper output portion 61, and the tray 30 is supported by the upper output portion 61 and does not come into contact with the support portion 41 of the support container 40. Listed in. The main body part 20 with the upper container 10 and the cover 50, the support container 40, and the upper output part 61 with the tray 30 mounted thereon are mounted on the lower output part 62. Thereby, the gravity of the tray 30 acts on the upper output portion 61, and the gravity of the upper container 10, the main body portion 20, the support container 40, and the cover 50 does not act on the upper output portion 61. That is, when the tray 30 receives excrement, the upper output unit 61 does not detect the weights of the upper container 10, the main body 20, the support container 40, the cover 50, and the animal, but does not detect the weight of the tray 30 and the excrement. Is detected by the upper load cell. The absorbent sheet is loaded as the weight of the tray 30, and the excrement disposal agent is loaded as the weight of the upper container 10.

Explain specifically how to measure the weight of excrement. The storage unit stores in advance the weight detected as the force received by the upper load cell and the weight detected as the force received by the lower load cell 63 when the animal is not placed on the animal litter box. That is, the result of detecting the weight of the tray 30 and the absorbent sheet by the upper load cell is used as the initial tray weight, and the weight of the upper container part 10, the main body part 20, the support container 40, the cover 50, and the excrement disposal agent is detected by the lower load cell. The result is stored as the initial body weight in the storage unit in advance.

When an animal such as a cat enters the inside of the upper container 10 from the front side of the animal litter box 1, the force received by the lower load cell 63 increases as the weight of the upper container 10 (main body portion 20) increases. At this time, the lower load cell 63 outputs a signal according to the received force. The control unit that received the signal stores the detection result received as the signal as the weight before excretion in the storage unit, and the processing unit calculates the difference between the weight before excretion and the initial body weight stored in the storage unit. Obtain the weight of the animal.

When the animal urinates on the bottom 11 of the upper container, the urine falls through the gap between the excrement disposal agents and the through hole h to the receiving portion 31 of the lower tray 30. As a result, the weight of the tray 30 that has received urine increases, the force that the upper load cell receives from the tray 30 increases, and the signal that corresponds to the force that the upper load cell receives from the tray 30 is output. The control unit stores the detection result received as a signal as the post-excretion tray weight. In the processing section, the difference between the initial tray weight stored in the storage section and the post-excretion tray weight is calculated to obtain the weight of animal excrement (urine).

The control unit can transmit the obtained weight of excrement to the user's terminal via the communication unit and display it on the terminal screen. The control unit is not limited to the weight of excrement, and may transmit and display various types of obtained data. The various data obtained are the number of excretions, the time of excretion, the weight of the animal, and the like. Further, the accumulation of each data may be shown in a graph or a table.

<< Regarding Opening Region H and Tray Contact Part 61a >>
FIG. 12 is a diagram for explaining the arrangement of the tray contact portion 61a, the opening area H, and the receiving portion 31. In FIG. 12, for convenience, the tray contact portion 61a and the receiving portion 31 which are not visible are shown by solid lines. As shown in FIG. 12, the length Lh in the front-rear direction of the opening area H is shorter than the length Ls in the front-rear direction of the tray contact portion 61a (Lh <Ls), and the length of the rear portion of the tray contact portion 61a is The end is located on the front side of the rear end of the receiving portion 31. Further, the horizontal length Mh of the opening area H is shorter than the horizontal length Ms of the tray contact portion 61a (Mh <Ms).

Further, the tray contact portion 61a of the animal litter box 1 is narrower than the receiving portion 31 of the tray 30 and is provided inside the receiving portion 31 of the tray 30. In other words, the length Ls of the tray contact portion 61a in the front-rear direction is shorter than the length Lt of the receiving portion 31 in the longitudinal direction, and the length Ms of the tray contact portion 61a in the left-right direction is equal to the left-right direction of the receiving portion 31. Is shorter than the length Mt. The receiving portion 31 is an area for receiving excrement (urine), and preferably has a wider area in order to reduce the risk of excrement leaking to the outside of the tray 30 or the outside of the animal litter box 1. Is. It is also an area for disposing the absorbent sheet, and by disposing the absorbent sheet wider, it becomes easier to absorb excrement faster.

However, the tray 30 of the animal litter box 1 in use is in a state of being supported by the upper output part 61 by being placed on the tray contact part 61a. The tray contact portion 61a is narrower than the area of the receiving portion 31, and the bottom surface of the receiving portion 31 has a portion that is not in direct contact with the tray contact portion 61a. Generally, when the animal excretes toward the rear side of the animal litter box 1, the excrement is likely to accumulate behind the tray 30. Conventionally, when an animal litter box is used in which the rear end of the tray contact part is located on the front side of the rear end of the receiving part, excrement that falls in a region behind the tray contact part in the front-rear direction of the tray. Upon receiving an object, the tray becomes unstable, and the excrement measurement is more likely to be inaccurate than when the excrement is received in an area that overlaps the tray contact portion of the receiving portion in the vertical direction. If excrement accumulates in the area of the receiving part that is not in contact with the tray contact part and the unstable state becomes large, the tray may tilt or the tilted tray may contact the main body or the support container. Then, the weight of the excrement (the weight of the tray that received the excrement) may not be accurately measured.

In this respect, as in the animal litter box 1, by providing the rear end of the hole area H at the same position as the rear end of the tray contact portion 61a or in front of the rear end of the tray contact portion 61a, the upper container The excrement that falls from the tray 10 to the tray 30 can be easily dropped into the area of the tray contact portion 61a. As a result, the bottom surface of the tray 30 can be brought into stable contact with the tray contact portion 61a and the excrement can be received in a stable state. Therefore, the weight of the excrement (the weight of the tray 30 having received the excrement) can be reduced. It is easy to measure accurately.

FIG. 13 is a diagram for explaining the tray 30 and the support container 40 in a used state and in a state in which the tray 30 is arranged near the front side wall portion 42a side in the front-rear direction. The distance in the front-rear direction from the rear end of the hole area H to the rear end of the tray contact portion 61a is defined as a first distance L1 (FIG. 12). Further, as shown in FIG. 13, when the tray 30 is in use, and the tray 30 is arranged closer to the frontmost side wall portion 42a in the front-rear direction, the tray 30 is located at the center in the left-right direction (center line CC). The distance between the rear end and the rear end of the inner region 42U is the second distance L2. As shown in the enlarged view of FIG. 13, the second distance L2 is the distance between the rear end 30e of the tray 30 and the rear end 42Ue of the inner area U at the center line CC. At this time, it is preferable that the first distance L1 is equal to or greater than the second distance L2 (L1 ≧ L2). In other words, in the use state, the state where the tray 30 is arranged closer to the front side wall portion 42a side in the front-rear direction is that the tray 30 is closer to the front side by the second distance L2 than the state where the tray 30 is closest to the rear side wall portion 42d. Only move. Therefore, even when the tray 30 is closest to the front side in the use state, by setting the first distance L1 to be the second distance L2 or more, the excrement that falls from the upper container 10 to the tray 30 is prevented from contacting the tray contact portion. It becomes easy to receive in the area | region which overlaps with 61a in the up-down direction. As a result, the bottom surface of the tray 30 is brought into contact with the tray contact portion 61a in a stable state, the excrement is likely to be received in a stable state, and the weight of the excrement is more easily measured.

Further, the length of the main body concave portion 25 of the main body portion 20 in the front-rear direction is M25 (FIG. 5), and the length of the support container convex portion 44 of the support container 40 in the front-rear direction is L44 (FIG. 9). At this time, assuming that the difference between the length M25 and the length L44 is the third distance L3 (L3 = M25−L44), the distance in the front-rear direction from the rear end of the opening area H to the rear end of the tray contact portion 61a. It is more preferable that the first distance L1 (FIG. 12) is equal to or larger than the third distance L3 (L1 ≧ L3). In the use state, the support container convex portion 44 is fitted in the main body concave portion 25, but the support container convex portion 44 can move in the front-rear direction inside the main body concave portion 25 by the third distance L3. When the support container convex portion 44 is located on the frontmost side of the main body concave portion 25, the support container 40 is closer to the front side by the third distance L3 than when the support container convex portion 44 is located on the rearmost side of the main body concave portion 25. .. That is, the receiving portion 31 of the tray 30 is located closer to the front side by the third distance L3. Therefore, by setting the first distance L1 to be equal to or greater than the third distance L3, it becomes easy to receive the excrement that falls from the upper container 10 to the tray 30 in a region that vertically overlaps the tray contact portion 61a. As a result, the bottom surface of the tray 30 is brought into contact with the tray contact portion 61a in a stable state, the excrement is likely to be received in the stable state, and the weight of the excrement can be more accurately measured.

Furthermore, it is more preferable that the first distance L1 is equal to or more than the sum of the second distance L2 and the third distance L3 (L1 ≧ L2 + L3). Even when the animal is excreted toward the rear side of the animal litter box 1 in the fitted state where the tray 30 is closest to the front side wall portion 42a and the support container 40 is arranged at the frontmost side, the upper container The excrement that falls from the tray 10 onto the tray 30 can be easily dropped within a region that vertically overlaps the tray contact portion 61a. As a result, the gravity of the tray 30 can be easily applied to the tray contact portion 61a in a stable state, and the weight of excrement can be more accurately measured.

As shown in FIG. 12, one side edge (for example, the left side) of the opening area H in the left-right direction is at the same position as the one side edge (left side) of the tray contact portion 61a, or the tray contact portion 61a has the same position. It is preferable that the contact portion 61a is provided inside the one side (left side) side end. By doing so, even when the animal excretes toward one side in the left-right direction of the animal litter box 1, the excrement is discharged while the bottom surface of the tray 30 is in stable contact with the tray contact portion 61a. Can receive. Therefore, the excrement is accumulated on one side of the tray 30 in the left-right direction, and the excrement is accumulated in the area of the receiving portion 31 that is not in contact with the tray contact portion 61a, and the tray is inclined, or the inclined tray 30 is It is possible to reduce the risk of contact with the main body 20 and the support container 40, and it becomes easier to measure the weight of excrement more accurately.

One side (left side) of the tray contact portion 61a from a side end on one side (for example, left side) of the opening area H in the center (center line XX) in the front-rear direction of the inner area 42U. The length to the end is the fourth distance L4. Further, in the center line XX of the inner area 42U, the left-right length of the inner area 42U is MU, and the left-right length of the outer shape of the tray 30 is M30. The difference between the left-right length MU of the inner area 42U and the left-right length M30 of the tray 30 is defined as a fifth distance L5 (L5 = MU−M30). At this time, it is preferable that the fourth distance L4 is equal to or greater than the fifth distance L5 (L4 ≧ L5). The tray 30 is movable in the left-right direction within the inner region 42U by the length of the fifth distance L5. Even when the animal is excreted toward one side in the left-right direction of the animal litter box 1 in the state where the tray 30 is brought close to the side of the wall section 42 on one side in the left-right direction (for example, the left side wall section 42b), By setting the 4th distance L4 to be equal to or greater than the 5th distance L5, the excrement falling from the upper container 10 to the tray 30 is easily received within the region overlapping the tray contact portion 61a in the vertical direction. As a result, the bottom surface of the tray 30 is brought into contact with the tray contact portion 61a in a stable state, the excrement is likely to be received in the stable state, and the weight of the excrement can be more accurately measured.

Further, as shown in FIG. 6, on the center line XX, the length of the supporting container 40 in the left-right direction is M40, and from the inner end of the main body side wall 24 on one side in the left-right direction to the main body side wall on the other side. When the distance to the inner end of 24 is M20, the difference between the length M40 and the distance M20 is the sixth distance L6 (L6 = M20−M40). At this time, it is preferable that the fourth distance L4, which is the length from the one side end of the opening region H in the left-right direction to the one side end of the tray contact portion 61a, is not less than the sixth distance L6. (L4 ≧ L6). In the use state, the support container 40 housed in the main body 20 can move in the left-right direction by the sixth distance L6. Even when the animal is excreted toward one of the left and right sides of the animal litter box 1 in the state where the support container 40 is brought close to the one side of the main body side wall portion 24 on the one side in the left and right direction, the fourth distance L4 is set to a sixth distance or more. By doing so, it becomes easy to receive the excrement that falls from the upper container 10 to the tray 30 in the area that overlaps the tray contact portion 61a in the vertical direction. As a result, the bottom surface of the tray 30 is brought into contact with the tray contact portion 61a in a stable state, the excrement is likely to be received in the stable state, and the weight of the excrement can be more accurately measured.

Furthermore, it is more preferable that the fourth distance L4 is equal to or more than the sum of the fifth distance L5 and the sixth distance L6 (L4 ≧ L5 + L6). With the tray 30 being brought close to the wall portion 42 on one side in the left-right direction, and the support container 40 being brought close to the side wall portion 24 on the one side in the left-right direction, the animal faces one side in the left-right direction of the animal litter box 1. Even when excreted by excretion, the excrement that falls from the upper container 10 to the tray 30 is easily received in a region overlapping the tray contact portion 61a in the vertical direction. This allows the tray 30 to stably contact the bottom surface of the tray 30 with the tray contact portion 61a, to easily receive the excrement in a stable state, and to more easily measure the weight of the excrement.

FIG. 14 is a schematic view of a cross section taken along the line BB in FIG. In FIG. 14, the main body portion 20 and the like represent a portion that is not a cross section, but are hatched for convenience. Further, the open area H is also shown in a simplified sectional view. As shown in FIG. 14, the distance W in the front-rear direction from the rear end of the open area H to the rear end of the receiving portion 31 is such that the lower surface of the upper container 10 (the bottom surface of the upper container bottom 11) and the receiving portion 31 are separated from each other. It is preferably longer than the distance T from the upper surface (W> T). For example, the animal is excreted in a state of facing the rear of the animal litter box 1, and the excrement (urine) has an incident angle θ of 45 degrees from the front toward the rear end of the open area H and the upper container 10 When it falls further downward or when it enters the tray 30, the receiving portion 31 receives most of the excrement in a region separated from the opening region H by a distance T. That is, by making the distance W longer than the distance T, even when the animal excretes in a state of facing the rear of the animal litter box 1, the receiving portion 31 can receive the excrement more reliably and the tray 30 It is possible to reduce the risk of excrement leaking backward.
