Description

BACKGROUND OF THE INVENTION The present invention relates to a litter tray for toilet training of pets, and more particularly, to a litter tray that induces a pet to defecate on the tray using a preset sound source, detects defecation on the tray, and outputs a preset sound (such as encouragement or praise) based on whether defecation has occurred, thereby enabling the pet to be encouraged or praised even in the absence of the pet owner. In general, a pet refers to an animal that lives together with humans, not merely as a toy but as a companion whose presence and benefits to humans are respected. The term encompasses a variety of animals—such as dogs, cats, and more—depending on the owner's preferences. As most pets live indoors, they require various forms of training, including toilet training. Accordingly, a wide range of efforts have been made to improve the effectiveness of such training and to develop the intelligence of pets. Typically, toilet training for pets involves laying several layers of newspaper on the floor. When the pet shows signs of defecation or urination, the owner places the pet on the newspaper and waits until it finishes. Through repetition, the pet learns to use the newspaper as a toilet area. Alternatively, a toilet tray or pad may be used in place of newspaper. Layering the newspapers serves to retain the pet's urine odor on the bottom layers, which helps attract the pet back to the same spot in the future by recognizing its own scent. However, this method requires considerable time and effort from the pet owner, making consistent training difficult. As a solution to such problems, Korean Patent Publication No. 10-2021-0045261 discloses a pet toilet training device. In this prior art, when a dog defecates on a pad, a temperature sensor detects the event, and a treat stored inside the main body is dispensed through an outlet. However, this conventional technology has a drawback in that it cannot provide differentiated feedback based on the pet's specific type of excretion. Therefore, there is a need for a toilet training tray for pets that outputs a familiar voice of the owner instead of treats, allowing pets to be toilet-trained through encouragement and praise even in the absence of the owner. SUMMARY OF THE INVENTION The present invention is intended to solve the aforementioned problems, and its object is to provide a toilet training tray for pets that induces a pet to defecate on the tray using a preset sound source, detects defecation on the tray, and, depending on whether defecation has occurred, outputs a preset sound (such as encouragement or praise), thereby enabling the pet to be encouraged or praised even in the absence of the pet owner. The problems to be solved by the present invention are not limited to those mentioned above, and other problems not specifically stated will be clearly understood by those skilled in the art from the following detailed description. To address the aforementioned problems, the toilet training tray for pets according to the present invention comprises: a horizontal plate placed on the floor and provided with a mesh-type toilet surface spaced apart from its upper surface; a vertical plate integrally formed with the horizontal plate and extending vertically from one end of the horizontal plate; a dispenser disposed at an upper portion of the vertical plate, configured to supply food and water for a pet; a dispensing tray disposed below the dispenser to receive the supplied food and water; and a control module comprising a processor, configured to identify pressure points through at least one pressure sensor installed inside the horizontal plate, determine urination when three pressure points are detected, and determine defecation when four pressure points are detected, and output a preset sound through a speaker mounted on one side of the vertical plate based on the determination. The toilet training tray may further comprise a hemispherical roll case located at the intersection of the horizontal and vertical plates, which houses a roll-type toilet sheet wound in a roll form. The roll-type toilet sheet may be cut by external force to a size similar to the area of the toilet surface and placed thereon. The roll case may include: a magnetic openable cover; a first support wall into which a central hole of the roll-type toilet sheet is inserted and fitted, the first support wall being provided with a central shaft to mount the sheet; a second support wall facing the first support wall and integrally formed with the openable cover, the second support wall opening and closing simultaneously with the cover; and a third support wall contacting the cover, wherein the third support wall may include a cutting section arranged along its upper surface to sever the toilet sheet. The roll case may further comprise: a cover portion attached to the exterior of the roll case to allow easy cleaning of waste adhered during pet excretion; and a gripping portion
