Description
CROSS-REFERENCE TO RELATED APPLICATION

This application is a Section 371 of International Application No. PCT/KR2015/001116, filed Feb. 3, 2015, which was published in the Korean language on Aug. 11, 2016, under International Publication No. WO 2016/125927 A1, the disclosure of which is incorporated herein by reference.


TECHNICAL FIELD

The present invention relates to an excreta disposal apparatus for automatically disposing an excreta discharged from a human body, and more particularly, to an excreta disposal apparatus provided with a rotary nozzle that can wash a large area of a disposing space.


BACKGROUND ART

In general, since the patients or the elderly, who have mobility difficulties or who are unable to move their lower body by their own will, do not have the ability to handle their own excreta, there is an inconvenience that a guardian or a caregiver should always reside at hand.


Therefore, in order to solve such an inconvenience, an excreta disposal apparatus for collecting excreta by directly contacting the body has been researched and developed. Such an excreta disposal apparatus is designed to receive and suck a user's excreta and discharge the excreta to the outside so that the excreta can be automatically treated even if the guardian or the caregiver does not reside around the user.


However, since the disposal apparatus is designed without considering the body of the user and is concentrated only on the function of the excreta disposal, the conventional excreta disposal apparatus developed to date has a problem that the usability is very low. Generally, since a part around the buttocks or the genital area where excreta is excreted is sharply curved and the excreta disposal apparatus is difficult to adhered, there are many cases where the excreta leaks out between the human body and the excreta disposal apparatus.


In addition, the users, such as the patients or the elderly, who use the excreta disposal apparatus often live in a bed and frequently cannot change their posture on their own. When such a state persists for a long time, a bedsore occurs, so that it is necessary to periodically change the posture. However, since the posture cannot be changed in the state where the excreta disposal apparatus is worn, there is an inconvenience to remove the excreta disposal apparatus.


In addition, when the user discharges the excreta to the excreta disposal apparatus, much effort is required to wash it. In order to solve this problem, a nozzle for spraying washing water may be provided in a space in which the excreta is received. However, in this case, since the washing can be performed only in a restricted area, the effect is insignificant, and the number of nozzles is inevitably increased.


Therefore, a method for solving such problems is required.

FIG. 6 is a perspective view of the rotary nozzle 240 in the excreta disposal apparatus according to an embodiment of the present invention.


As shown in FIG. 6, the rotary nozzle 240 is exposed to the disposal space, and in particular, in the present embodiment, is exposed to the excrement disposal unit T1. The rotary nozzle 240 is provided so as to rotate about a central axis, and sprays the washing water. One or more spray holes 242 for spraying washing water is formed in the circumference of the rotary nozzle 240.


Particularly, in the present embodiment, the spray holes 242 are arranged in double columns, and the spray holes 242 of each column are alternately arranged so as not to interfere with each other.


The rotation of the rotary nozzle 240 may be performed in various directions. For example, the rotary nozzle 240 may rotate in various directions such as up and down, left and right, and diagonal directions, and may spray the washing water.



FIG. 7 is a perspective view of the washing unit in the excreta disposal apparatus according to an embodiment of the present invention.


As shown in FIG. 7, the washing unit includes the rotary nozzle 240 and elements associated with the rotary nozzle 240.


In the present embodiment, the washing unit includes the rotary nozzle 240, a motor 260 for generating a rotational driving force, a gear unit 262, 264, 266 which is rotated by the motor 260 and transmits a rotational force to the rotary nozzle 240, a shielding member 250 which receives a part of the rear side of the rotary nozzle 240 and shields the inside of the accommodation space from the disposal space, and a housing 270. Further, although not shown, a controller for controlling each element of the washing unit may be further included.


The gear units 262, 264, 266 may include a plurality of gears, which may be implemented in various forms. The shielding member 250 is formed with a groove for supporting a rotation shaft 244 of the rotary nozzle 240, accommodates a part of the rear side of the rotary nozzle 240, and is mounted in the body of the excreta disposal apparatus, thereby preventing the excreta of the disposal space or the washing water from flowing into the accommodation space. That is, among the elements of the washing unit, the rotary nozzle 240 and the front surface of the shielding member 250 shall be exposed to the disposal space.


The controller is provided to control the movement of the motor 260. When the excreta is detected in the disposal space by a detection sensor or the like, the controller can rotate the motor 260 in the forward and reverse directions, and spray the washing water through the rotary nozzle 240. In addition, it is obvious that the controller may be preset to control the washing unit in various situations.


Meanwhile, a detection sensor including an excrement detection sensor and a urine detection sensor is provided in the disposal space so as to sense the presence or absence of excreta, and to control each element when it is determined that excreta exists.



FIG. 8 is a cross-sectional view showing a rotation range in an area where the rotary nozzle 240 is exposed to the disposal space, in the excreta disposal apparatus according to an embodiment of the present invention.


As shown in FIG. 8, the rotary nozzle 240 has a rotation range of a certain angle in an area exposed to the disposal space. In the present embodiment, the rotary nozzle 240 rotates in a range between the upper end and the lower end of the shielding member 250 and is able to spray the washing water to the disposal space and the buttocks or genital area of a user.


That is, according to the present invention, since the rotary nozzle 240 can occupy a very small space and can spray the washing water over a wide range, the overall structure is simplified, the buttocks and genital area of the user can be washed by using only the minimum number of nozzles, and an entire disposal space can be washed.


Meanwhile, for more effective washing, the rotary nozzle 240 may be provided at a position corresponding to a user's anus in a state where the user's body is seated on the seating unit. That is, when the rotary nozzle 240 is provided at a position facing the user's anus, a surrounding area can be uniformly washed around the anus of the user.


More specifically, the rotary nozzle 240 may be provided in such a manner that a center of rotation angle of the area exposed to the excrement disposal unit is provided at a position corresponding to the anus of the user. The reason for this is that the same area in the upper and lower directions around the anus can be washed as the position of facing the anus becomes the center of the rotation angle.



FIG. 9 is a cross-sectional view showing a state in which a rotary nozzle washes a shielding member, in an excreta disposal apparatus according to an embodiment of the present invention.


As shown in FIG. 9, the rotary nozzle 240 may be rotated so that the spray hole 242 can face the direction of the shielding member 250 to wash the surface of the shielding member 250. That is, since it is difficult to wash manually between the rotary nozzle 240 and the shielding member 250, the shielding member 250 may be washed by the rotary nozzle 240, thereby improving convenience.


This may be implemented by controlling the motor by the controller so as to rotate the rotary nozzle 240 in the direction of the shielding member 250, immediately after the disposal of the excreta is completed.


Although the exemplary embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Accordingly, the scope of the present invention is not construed as being limited to the described embodiments but is defined by the appended claims as well as equivalents thereto.
