The second motion sensor 270 is a sensor that detects whether the companion animal is located inside the chamber part 100 by irradiating ultrasonic waves into the area where the through hole 143 is formed.

In one embodiment, the first motion sensor 230 detects whether a companion animal exists in the lower side of the chamber part 100, and the second motion sensor 270 irradiates ultrasonic waves at the center height of the chamber part 100 to return the animal. The presence or absence of an animal can be detected, allowing precise detection regardless of the size of the pet. In addition, the controller 250 may control the operation of the sterilization sensor 240 according to a detection result of at least one of the first motion sensor 230 and the second motion sensor 270.

For example, if the pet size is small, the control unit 250 may control the sterilization sensor 240 to operate only by the detection result of the first motion sensor 230, and if the pet is relatively large, the first operation may be performed. The operation of the sterilization sensor 240 may be controlled by referring to the detection result of the sensor 230 and the second motion sensor 270.

The motor 280 provides power for rotating the shaft gear 141 in one direction. A driving gear 281 is provided at one side of the motor 280, and the driving gear 281 may be engaged with the shaft gear 141 to rotate together. In addition, the pair of

During the rotation of the chamber unit 100, the excrement collecting unit 300 may collect the excrement 30 located in the lower side of the chamber 100 to collect.

In addition, at least a portion of the excrement collector 300 may be formed to be inclined with respect to the chamber shaft 140. In addition, the excrement 30 is carried by the excrement collector 300 during the rotation of the chamber 100 moves by the weight along the inclined surface of the excrement collector 300, and naturally to the outside of the chamber 100 May be discharged.

In an embodiment, the excrement collector 300 may include a first region 310 and a second region 320. The first region 310 may be formed to be inclined at a predetermined angle with respect to the chamber rotating shaft 140 so that the collected excrement 30 is lowered in a predetermined direction by its own weight. In addition, a plurality of sand separation holes 312 and 313 are formed in the first region 310 so that the sand 20 carried by the excrement collecting unit 300 quickly moves to the lower side of the chamber 100. Can fall.

In one embodiment, a portion of the first region 310 is in close contact with the first inner wall 110 of the chamber portion 100, and another portion of the first region 310 is the second inner wall 120 of the chamber portion 100. ) And another part of the first region 310 may be in close contact with the third inner wall 130. In this case, a portion of the first region 310 that contacts the third inner wall 130 is called an intimate portion 311.

As shown in FIG. 7, the close-contacted portion 311 of the first region 310 is formed by the motor 280 when the first region 310 contacts the sand 20 and lifts the sand 20. It may be formed in a twisted shape to reduce the load on the rotating shaft. If the collecting portion for contacting the sand 20 and spreading the sand 20 is formed in a straight line, the sand 20 is brought into contact with the entire region of the collecting portion, so that a large amount of the sand 20 is scattered at once. As a result, the driving load may be excessively applied to the rotating shaft of the motor 280, thereby causing a burden on the motor 280, and the power consumption of the motor 280 may increase.

However, in one embodiment, by forming the close portion 311 in a twisted structure, the amount of sand 20 to be sprinkled during rotation of the chamber 100 may be relatively reduced, thereby reducing the durability and power of the motor 280. To contribute to.

The second region 320 may include the excrement 30 positioned on the first region 310 so as to move to the excrement outlet 121 formed in the second inner wall 120 of the chamber part 100. It may extend from one end and may be formed to be inclined in a different direction from the first region 310. As shown in FIG. 6, a portion of the second region 320 may be in close contact with the second inner wall 120. The end of the second region 320 may be seated in the discharge passage 150 and supported by the discharge passage 150.

In one embodiment, when the chamber part 100 rotates in one direction, the excrement collector 300 rotates together with the chamber part 100 to pour out the excrement 30 located below the chamber part 100. . In this case, the first region 310 is in close contact with the first inner wall 110, the second inner wall 120, and the third inner wall 130, and the second region 320 is in close contact with the second inner wall 120. Since the excretion 30 located on the first region 310 during the rotation of the chamber part 100 does not fall to the lower side of the chamber part 100, the excrement discharge port moves in the direction of the ground 40 by its own weight. The moving direction toward 121 may be naturally discharged to the outside of the chamber part 100. In addition, as the first region 310 and the second region 320 remain in close contact with each inner wall, it is possible to utilize the internal space of the chamber part 100 widely.

A detailed process of discharging the excrement 30 to the outside of the chamber part 100 by the rotation operation of the chamber part 100 will be described in detail with reference to FIG. 8 below.

The scaffold support 512 may protrude from the lower side of the scaffold housing 510 to support the chamber part 100 together with the

storage supporters

430, 440, and 450.

In one embodiment, the control unit 250 may control the operation of the sterilization sensor 240 by comprehensively determining the detection result of the first motion sensor 230, the second motion sensor 270, and the entrance sensor 511. And, the rotation of the chamber unit 100 can be controlled.

For example, when the entrance sensor 511 detects that the pet enters the entrance 111, the controller 250 may first determine that the pet has entered the chamber part 100. In addition, when the first motion sensor 230 detects a companion animal located below the chamber unit 100, the controller 250 may secondly determine that the companion animal is located inside the chamber unit 100. . Of course, according to the size of the companion animal, the controller 250 may determine whether the companion animal is present in the chamber part 100 by referring to the detection result of the second motion sensor 270.

When the companion animal leaves the chamber part 100 through the doorway 111 after the bowel movement is completed, the controller 250 may include the first motion sensor 230, the second motion sensor 270, and the entrance detection sensor 511. Through the detection result of the pet can confirm that the pet is not located in the chamber portion (100). Therefore, the control unit 250 controls the chamber unit 100 to rotate in one direction by operating the motor 280 after a predetermined time elapses, and when the rotation is made by a predetermined number of rotations, the chamber unit 100 is controlled. After stopping, the sterilization sensor 240 is operated for a predetermined time so that the sterilizing light is irradiated into the chamber part 100.

In addition, when the entrance sensor 511 detects the companion animal while the sterilization sensor 240 is operating, the control unit 250 stops the operation of the sterilization sensor 240, so that the companion animal is sterilized light (for example, , Ultraviolet rays) can be prevented.

The leak prevention part 600 may be mounted to the doorway 111 in the chamber part 100. In one embodiment, the spill prevention part 600 is fixedly coupled to the first inner wall 110 and may be mounted along at least a part of the circumference of the entrance 111. In addition, the spill prevention part 600 is formed in a U-shaped semi-cylindrical structure and coupled with the doorway 111 when the position of the doorway 111 is close to the ground 40 due to the rotation of the chamber part 100. The sand 20 may be prevented from flowing out of the chamber part 100 through the doorway 111.

In addition, the spill prevention part 600 serves as a foothold for supporting the foot of the pet at the moment when the pet enters the entrance 111, the first step, the pet is more stable inside the chamber portion 100 To get in.

frames

710 and 720 so that wires for electrically connecting the components of the chamber driver 200 and the excrement collector 300 may be inserted into the

frames

710 and 720.

In addition, the

frames

710 and 720 evenly distribute the load generated on one side when the chamber part 100 rotates in the other direction (for example, the direction of the excrement collecting part 300 from the chamber driving part 200), An eccentricity that may occur in the secondary rotation shaft 140 may be prevented and the chamber portion 100 may be more stably rotated.

Furthermore, the

frames

710 and 720 according to an embodiment may distribute the load in the other direction of the chamber part 100 when the chamber driving part 200 rotates the chamber part 100 on one side of the chamber part 100. Therefore, the load of the motor 280 may be reduced, thereby improving durability of the motor 280.

Meanwhile, in FIG. 9, the rotation axis 160 refers to an imaginary line that is the same as the chamber rotation axis 140 or parallel to the chamber rotation axis 140. As the first region 310 is formed to be inclined by an angle (α °) formed by the rotation axis 160 and the first inclination line 314 when the rotation axis 160 is a reference, the first region 310 is formed. Excretion 30 spun on the) may be induced to move in the direction of the second inner wall 120 by its own weight.

In addition, in FIG. 8E, when the second region 320 is based on the center line 170, the second region 320 is formed to be inclined by the angle β ° formed by the center line 170 and the second inclination line 321. Accordingly, the excrement 30 moved to the second inner wall 120 can naturally move to the excretion discharge port 121 by its own weight. In FIG. 8E, the center line 170 is perpendicular to the ground 40, and means a line passing through the center point of the excretion discharge port 121, and the ground 40 means a surface contacting each support.

FIG. 10 is a perspective view schematically illustrating a state in which a chamber part fastening device is opened and a chamber part is separated in an upward direction in a companion animal waste treatment apparatus according to an embodiment of the present invention. Referring to FIG. 10, the chamber part fastening device 212 is moved to the center of the hinge shaft 2121 when an external force is applied in an upward direction, thereby exposing the chamber part rotating shaft 140 to the outside. Therefore, the user may lift the chamber unit 100 upwardly from the ground as it is to separate only the chamber unit 100 separately.

That is, in one embodiment, since the chamber part 100 can be easily separated by the axial movement of the chamber part fastening device 212, the process of separating and combining the chamber part 100 is convenient, and in the chamber part 100. Since it is not provided with a separate electronic component, only the chamber part 100 can be separated and washed with water, and the bowel space of the pet can be maintained in a more comfortable state.

As described above, the companion animal waste treatment apparatus 10 according to an embodiment of the present invention is to minimize the area of the excrement collecting unit 300 located inside the chamber 100 of the excrement collection unit 300 Since the first region 310 and the second region 320 remain in close contact with the inner wall of the chamber 100, the inner space of the chamber 100 may be widely used. That is, there is an advantage that it is possible to accommodate the large pets without expanding the size of the chamber portion 100 unreasonably, and the pets introduced into the chamber portion 100 can be more comfortably defecated.

In addition, in one embodiment, the excrement collector 300 boards at least a portion of the first region 310 and the second region 320 to maximize the internal space of the chamber 100 by minimizing its volume. ) Can be formed.

In addition, since the excrement collector 300 is formed to be inclined with respect to the rotation axis of the chamber 100, the excrement located on the bottom of the chamber portion 100 during the rotation of the chamber portion 100 even if the chamber portion 100 is not tilted ( It is easy to separate the 30 to the outside of the chamber 100. When the chamber is inclined, a configuration for stably supporting the chamber must be added, thereby increasing the volume of the excreta processing device and requiring more power to rotate the inclined chamber, but according to one embodiment, the animal feces The processing apparatus 10 can stably support the chamber portion 100 because the chamber portion 100 is disposed to be substantially horizontal to the ground 40, and compared with the power required to rotate the inclined chamber during rotation. The chamber unit 100 can be rotated with relatively little power.

In addition, in the companion animal waste treatment apparatus 10 according to an embodiment, the chamber driving unit 200, the excrement storage unit 400, and the scaffold unit 500 support the chamber unit 100 when the chamber unit 100 rotates. Therefore, a separate configuration for supporting the chamber unit 100 can be omitted, so that the overall configuration of the waste treatment apparatus can be simplified. That is, according to one embodiment of the present invention, the equipment durability is improved, the maintenance is easy, and the manufacturing cost is reduced by simplifying the configuration.

In addition, even when the chamber part 100 is not tilted inclined during the rotation of the chamber part 100, a process in which the excrement 30 is separated and discharged from the chamber part 100 may be performed by the self-weight of the excrement 30. The equipment can be operated with less power than it consumes.

In addition, the interior of the chamber portion 100 is made defecation can be continuously sterilized through the sterilization sensor 240 to block the odor and bacteria breeding caused by the excretion 30, to maintain the interior of the chamber 100 in a comfortable state It is possible to do In addition, the sand 20 can be recycled by sterilizing the sand 20 located below the chamber part 100, thereby reducing the cost of replacing sand.

In addition, the pet waste treatment apparatus 10 of the embodiment can prevent the outflow of the sand 20 even without a separate opening and closing means for opening and closing the doorway 111, it is convenient to enter and exit the pet.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings. However, since the above-described embodiments have only been described with reference to preferred examples of the present invention, the present invention is limited to the above embodiments.
