Further, in the above-described excrement suction device, preferably, the excrement receiving body is an excrement receiving container, and the excrement receiving container has an upper wall in which the exhaust port is formed, and a suction port which is the aforementioned The excrement is attracted to the excrement receiving container and is disposed on the upper wall; the partition plate partitions the inner space of the excrement receiving container, and is disposed in the inner space in the exhaust port and the suction a gap formed between the upper end of the partitioning plate and the upper wall, the air that is attracted to the excrement receiving container together with the excrement; and the flow path changing member in the foregoing The space is disposed between the partition plate and the exhaust port so as to face the gap, and the air flow path is made longer by being in contact with the air passing through the gap. According to the above configuration, the partition space is provided in the internal space of the excrement container. Further, a gap is provided between the upper end of the partition plate and the upper wall of the waste receiving container. Further, in the internal space, a flow path changing member that makes the air flow path longer by the contact of the air passing through the gap is disposed at a position facing the gap. According to this configuration, the air that is sucked into the excrement container together with the excrement is easily separated from the excrement and moisture (hereinafter referred to as excrement or the like). Thereby, the air in the excrement container is inhaled in a state of being separated from the excrement or the like, and it is possible to more effectively suppress contamination of the machine or the like which is disposed downstream of the intake port.

Further, it is preferable that the excrement suction device has a hose, and an end portion of the hose is connected to the excrement receiving container, and the excrement passes through the inside when the excrement is sucked; the box portion is mounted thereon a lid portion that can be opened and closed; the lid portion covers the excrement receiving container in the box portion from above in a closed state; and the suction port of the excrement receiving container located in the box portion in the lid portion The upper portion forms a hole for inserting the end portion of the hose; if the lid portion is closed, the end portion of the hose inserted into the hole enters the suction port. According to the above configuration, the lid portion of the box portion is provided with a hole for inserting an end portion (hereinafter also referred to as a hose end portion) of the hose for sucking excrement. Moreover, if the lid is closed, the end of the hose inserted into the hole will enter the suction opening formed in the upper wall of the waste container. According to this configuration, it is easy to insert and remove the hose end portion of the excrement container. Moreover, according to the above configuration, it is possible to suppress the situation in which the excrement is scattered from the opening of the end portion of the hose and the inside of the tank portion is contaminated when the end portion of the hose is pulled out.

According to the above configuration, the air taken in by the fan is returned toward the portion of the user's body that is abutted by the receiver. That is, according to the above configuration, the air that is sucked into the excrement containment body together with the excrement will circulate. According to this configuration, the air in the body of the excrement is separated from the excrement or the like and then inhaled, so that the effect of suppressing contamination in the device becomes more meaningful. [Effects of the Invention]

According to the excrement suction device of the present invention, when the air in the excrement receiving body is inhaled and the excrement is sent to the excrement receiving body, the air can be transported with less attraction. Thereby, the suction portion can be further miniaturized under the attraction force necessary for ensuring that the excrement is appropriately conveyed toward the excrement container. Further, according to the excrement suction device of the present invention, when the air in the excrement container is sucked, the bacteria and the like of the moisture and the excretion are less likely to be attracted together with the air. As a result, it is possible to suppress contamination of a machine or the like that is disposed downstream of the intake port. Further, according to the excrement suction device of the present invention, when the excrement receiving container as the excrement storage container is removed from the tank portion, it is possible to suppress contamination in the tank portion due to scattering of excrement.

Hereinafter, an excrement suction device according to an embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to a configuration example thereof. However, the embodiments described below are merely examples for facilitating the understanding of the present invention and are not intended to limit the present invention. In other words, the present invention can be modified or improved without departing from the scope of the invention. Moreover, of course, the equivalents thereof are also included in the present invention.

In the following description, the "height direction" refers to the height direction of the excrement suction device 1, and corresponds to the vertical direction when the excrement suction device 1 is placed on the horizontal plane. In addition, the "depth direction" refers to the depth direction of the excrement suction device 1, and is strictly equivalent to the longitudinal direction of the casing 31 to be described later.

<<Schematic configuration of the excrement suction device of the present embodiment>> First, the schematic configuration of the excrement suction device (hereinafter referred to as the excrement suction device 1) of the present embodiment will be described with reference to Figs. 1 to 3 . Fig. 1 is a view showing the appearance of the excrement suction device 1. Fig. 2 is a view showing a state in which the excrement suction device 1 according to the embodiment of the present invention is used, and is a view showing a portion of the excrement suction device 1 installed in the lower half of the user. Fig. 3 is a schematic cross-sectional view showing the basic configuration of the excrement suction device 1 according to the embodiment of the present invention. Further, in the cross section shown in Fig. 3, the washing water hose 52 and the gas return hose 53 which will be described later are not originally formed, but for convenience of explanation, the washing water hose is indicated by a broken line in the same figure. 52 and gas return hose 53.

The excrement suction device 1 is formed as shown in Fig. 1, and is used by a patient who is in trouble or who is in bed (hereinafter referred to as a user). Specifically, the user attaches the diaper P as shown in Fig. 2, and defecates in a lying state. In this way, the excrement suction device 1 can detect the excrement in the diaper P and attract it, and after the defecation, wash the inter-femoral portion of the user (particularly the portion on the back side) with the washing water. The excrement and the washing water are sucked into the excrement container 20 provided in the excrement suction device 1 and accumulated in the container.

More specifically, the cup diaper 10 is provided in the diaper P as follows. The adapter 10 is attached to the inter-strand portion of the user's body in order to receive the excrement. Further, a sensor (not shown) is attached to the bottom wall of the receptacle 10 opposite to the inter-strand portion of the user. When the sensor detects excrement (hereinafter referred to as excrement D), the excrement suction device 1 operates.

Further, as shown in Fig. 2, a plurality of types of hoses are connected to the adapter 10. The first type of hose is a hose for sucking excrement (hereinafter referred to as a suction hose 51). One end of the suction hose 51 (the end connected to the side of the adapter 10) penetrates the bottom wall of the adapter 10 and faces the space between the bottom wall of the adapter 10 and the inter-feature portion of the user. The other end portion of the suction hose 51 (the end opposite to the side connected to the adapter 10) is connected to the excrement container 20. When the excrement D received by the receptacle 10 on the bottom wall is sucked by the excrement suction device 1, it is transported to the excrement receptacle 20 by the inside of the suction hose 51.

The second type of hose is a hose for supplying washing water (hereinafter referred to as a washing water hose 52). The washing water hose 52 is formed as a flow path of the washing water supplied from the washing water supply unit 60 as the washing water supply unit illustrated in Fig. 3 . One end of the washing water hose 52 (the end on the side to which the adapter 10 is connected) passes through the adapter 10 and faces the inter-sleeve portion of the adapter 10 and the user (strictly speaking, the inter-femoral portion is located on the ventral side) The space between the part of the backrest side). Therefore, if the washing water is supplied from the washing water supply unit 60, the washing water will flow toward the portion of the user's body that is abutted by the adapter 10, that is, flowing into the washing water hose 52 toward the inter-strand portion. Finally, the one end side opening of the washing water hose 52 is ejected.

Further, the washing water sprayed toward the user's body is received by the adapter 10 and sucked by the suction hose 51 to be transported to the excrement container 20, similarly to the excrement D.

The third type of hose is a hose for air return (hereinafter referred to as a gas return hose 53). The gas return hose 53 is formed as a flow path for returning the air in the diaper P that is attracted together with the suction faeces P to the inside of the diaper P when the excrement D and the washing water are sucked by the suction hose 51. One end of the gas return hose 53 (the end on the side connected to the adapter 10) passes through the adapter 10 and faces the inter-sleeve portion of the adapter 10 and the user (strictly speaking, the inter-femoral portion is located on the ventral side The space between the part of the backrest side). The air that is attracted together with the waste D and the washing water, after passing through the inside of the excrement suction device 1, the air will flow toward the portion of the user's body that is abutted by the adapter 10, that is, the inter-femoral portion. The inside of the return hose 53 is finally discharged from one end side opening of the gas return hose 53.

In other words, the air in the diaper P circulates between the inside of the diaper P and the inside of the excrement suction device 1. Thereby, the odor at the time of defecation will be left inside the diaper P and inside the excrement suction device 1, and the odor can be suppressed from being scattered to the outside as much as possible.

<<Device configuration of the excrement suction device>> The device configuration of the excrement suction device 1 will be described with reference to Figs. 1 and 3 to 6 . Fig. 4 is a perspective view showing the appearance of the excrement container 20. Fig. 5 is a view showing the apparatus body 30, the excrement container 20 and the cassette tank 61, showing the first lid portion 32 and the second lid portion 33 of the apparatus main body 30, and the excrement container 20 and the card are set up.

The apparatus main body 30 is a main portion of the excrement suction device 1, and as shown in Fig. 1, is formed in a rectangular parallelepiped shape. Further, the apparatus main body 30 of the present embodiment is formed, for example, in a size that can be transported by a caregiver (subsidiary) of the user. However, the size of the device body 30 can be arbitrarily set.

The function of the apparatus body 30 will be described. The apparatus body 30 houses therein an excrement container 20, and the excrement D in the diaper P is sucked into the excrement container 20 by decompressing the inside of the excrement container 20. . More specifically, when the apparatus main body 30 decompresses the inside of the excrement container 20, the diaper facing the suction hose 51 connected to the excrement container 20 and the end portion of the suction hose 51 will be described. The inside of P (specifically, the space between the receptacle 10 and the inter-strand portion of the user) is decompressed. Thereby, the apparatus body 30 attracts the excrement D received by the adapter 10 in the diaper P to the excrement receptacle 20 via the suction hose 51. At this time, the apparatus main body 30 sucks the excrement D together with the washing water sprayed in the diaper P and the air fed back into the diaper P.

As shown in FIG. 3, the apparatus main body 30 has a tank unit 35 as a tank portion, an air intake and exhaust unit 40, and a washing water supply unit 60. These units are housed in the outer casing 31 of the apparatus body 30. Hereinafter, the tank unit 35, the intake and exhaust unit 40, the washing water supply unit 60, and the excrement receiving container 20 in each of the constituent devices of the excrement suction device 1 will be described.

The tank unit 35 is a bottomed box-shaped container made of ABS (phenenenitrile-butadiene-styrene copolymer synthetic resin), and an excrement container 20 can be housed inside. The box unit 35 has an open end at its upper end. That is, the excrement receptacle 20 in the tank unit 35 can be taken out from the upper end opening of the tank unit 35. Further, in the present embodiment, the box unit 35 is formed to have a slightly deep bottom shape in order to accommodate the entire excrement container 20, and has a height higher than the height of the excrement container 20.

Moreover, as shown in FIG. 3, the box unit 35 is disposed in the inside of the horizontally long outer casing 31, and is disposed in the space in the depth direction (that is, the longitudinal direction of the outer casing 31). More specifically, the outer wall of the outer casing 31 (the upper wall 31a of the outer casing) is provided with a substantially square opening (not shown) in the depth direction end portion. The case unit 35 is inserted into the outer casing 31 from the opening, and can be disposed at the end portion in the depth direction inside the outer casing 31. In the following description, the side in the depth direction which is the same as the side on which the tank unit 35 is disposed is referred to as the "near side", and the side opposite to the side on which the tank unit 35 is disposed is referred to as the "deep side".

Further, among the side walls of the tank unit 35, on the side wall of the end portion on the deep side in the depth direction, as shown in Fig. 3, a rectangular suction port 36 is formed. This suction port 36 is provided at an upper side portion of the side wall of the tank unit 35 at the end portion on the deep side. Further, as shown in FIG. 3, inside the tank unit 35, a suction filter 37 is provided in a space between the intake port 36 and the excrement container 20. The suction filter 37 is a flat member having a plurality of thicknesses.

Further, the suction filter 37 covers the intake port 36 in a state of being attached to the case unit 35. Thereby, the foreign matter in the air or the like will be caught by the suction filter 37 just before the air in the tank unit 35 passes through the suction port 36.

Further, as shown in FIGS. 3 and 5, a lid portion (hereinafter referred to as a first lid portion 32) for closing the upper end of the tank unit 35 is attached to the tank unit 35. The first cover portion 32 is formed by a portion of the upper casing wall 31a, and is provided in a state of being opened and closed by a hinge mechanism. In the present embodiment, as shown in FIG. 5, the first lid portion 32 is opened by raising the end portion on the deep side of the first lid portion 32.

On the other hand, in a state where the first cover portion 32 is closed, the upper end opening of the case unit 35 is completely covered. In the case where the box unit 35 has the excrement container 20 built therein, the first lid portion 32 covers the excrement container 20 in the box unit 35 from above.

Further, a through hole is formed in an end portion of the first lid portion 32 located on the near side. This through hole is a hole through which the end portion of the suction hose 51 is inserted, and is hereinafter referred to as a nozzle insertion hole 32a. Further, as shown in Fig. 6, in the inner surface (lower surface) of the first lid portion 32, a cylindrical projecting portion 32b is attached to the edge portion of the nozzle insertion hole 32a. The cylindrical projection 32b is a cylindrical body made of silicone, and an end portion of the suction hose 51 that passes through the nozzle insertion hole 32a is fitted inside. Further, the front end portion of the cylindrical projecting portion 32b is expanded in a flange shape. If the first lid portion 32 is closed in the state in which the excrement container 20 is housed in the tank unit 35, the front end portion of the flange-like cylindrical projection portion 32b will be formed above the excrement receiving container 20. The wall abuts and is in close contact with the excrement container 20.

Further, the tank unit 35 is provided with a detector 38 for detecting that the discharge capacity of the excrement or the like in the excrement container 20 has reached the upper limit of the management. The detector 38 is composed of a capacitance sensor. In a state in which the excrement container 20 is housed in the tank unit 35, the side wall of the tank unit 35 is placed at a position juxtaposed with the excrement container 20. Further, the detection method of the detector 38 is not limited to the electrostatic capacitance method, and may be, for example, an optical type or may be detected by an electrode provided in the excrement container 20.

The air intake and exhaust unit 40 is a mechanism that decompresses the tank unit 35 to suck the air in the tank unit 35, and discharges (returns) the sucked air into the diaper P via the gas return hose 53. The air intake and exhaust unit 40 is composed of a fan 41, a control power source 42, and a fan casing 43 shown in Fig. 3 .

The fan 41 is a suction portion of the air in the suction box unit 35, and is operated by electric power supplied from the control power source 42. When the power from the commercial power source supplied to the general household is received by the power receiving unit (not shown) of the apparatus main body 30, the control power source 42 is used for starting the fan 41. If the fan 41 is actuated by the supplied electric power from the control power source 42, the air in the tank unit 35 is sucked by the fan 41 via the intake port 36. In the present embodiment, the fan 41 is operated only when the excrement container 20 is housed in the tank unit 35.

Moreover, the output of the fan 41 of the present embodiment (in other words, the amount of intake per unit time) can be adjusted, and for example, the output can be appropriately changed in accordance with the type of the excrement D or the like.

Further, as shown in Fig. 3, the fan 41 is housed in a fan casing 43 which is a hollow box having a substantially rectangular parallelepiped shape. The fan case 43 is disposed in the outer casing 31 at a position adjacent to the case unit 35 as shown in the drawing. Further, among the side walls of the fan case cover 43, a through hole (hereinafter referred to as a communication hole 43a) is formed in a side wall facing the box unit 35. The communication hole 43a is disposed at a position continuous with the intake port 36 of the tank unit 35 as shown in FIG. In other words, the inside of the fan casing 43 communicates with the inside of the tank unit 35 via the intake port 36 and the communication hole 43a. Therefore, when the fan 41 is actuated, the air in the tank unit 35 is sucked through the intake port 36 and the communication hole 43a.

Further, the air sucked by the fan 41 is returned to the inside of the diaper P (strictly, the inter-strand portion of the user's body which is abutted by the adapter 10) via the gas return hose 53. More specifically, the gas return hose 53 enters the outer casing 31 through the upper casing wall 31a. Further, as shown in Fig. 3, the end portion of the gas return hose 53 (the end opposite to the side to which the adapter 10 is connected) is connected to the fan case cover 43. When the air sucked from the inside of the tank unit 35 is discharged into the fan casing 43 in this manner, the air is returned to the inside of the diaper P via the gas return hose 53 after passing through the deodorizing device (not shown). .

Further, in the present embodiment, in order to smoothly return the air to the inside of the diaper P, a part of the air sucked by the fan 41 is discharged to the atmosphere after passing through the deodorizing device in the excrement suction device 1. Thereby, a difference occurs between the air suction amount in the diaper P and the air return amount in the diaper P, and as a result, it is easy to return air to the inside of the diaper P.

The washing water supply unit 60 corresponds to a washing water supply unit, and is a mechanism that supplies washing water to the inter-strand portion of the user's body that is abutted by the adapter 10. In the present embodiment, the washing water supply unit 60 generates warm water and supplies the generated warm water as washing water. The washing water supply unit 60 is composed of a cassette tank 61, a warm water supply device 62, and a can 63 shown in Fig. 3 .

The cassette type tank 61 is a tank for storing raw water of the washing water, and is detachable from the apparatus main body 30. Specifically, in the outer casing 31, a portion of the end portion on the deep side (that is, an end portion on the opposite side to the tank unit 35) is disposed, and a can-shaped casing 63, which is a box-shaped container, is disposed. The can 63 can receive a cassette can 61 therein. Further, the upper end of the can 63 has an open end. That is, the cassette can 61 in the can 63 can be taken out from the upper end opening of the can 63. Further, in the present embodiment, the can 63 has a sufficient depth to accommodate the entire cassette 61.

Further, as shown in Figs. 3 and 5, a second cover portion 33 for closing the upper end of the can 63 is attached to the can 63. The second cover portion 33 is formed by a part of the upper wall 31a of the casing, and is provided in a state of being opened and closed by a hinge mechanism. In the present embodiment, as shown in FIG. 5, the second lid portion 33 is opened by lifting the end portion of the second lid portion 33 on the deep side. On the other hand, in a state where the second lid portion 33 is closed, the upper end opening of the can 63 is completely covered, and the upper portion of the cassette can 61 in the can 63 is covered by the second cover portion 33.

Further, a can lid 61a is attached to the bottom of the cassette can 61. In the can lid 61a, a valve (not shown) that opens when the can state is in a specific state is incorporated. Specifically, when the atmosphere opening cover 61b provided in the upper portion of the cassette tank 61 is opened, the valve in the can lid 61a is opened, and the water in the tank flows out to the outside of the tank. The water that has flowed out of the can is temporarily received by the can 63, and then flows from the can 63 toward the warm water supply device 62.

The warm water supply device 62 warms the water received from the can 63 by generating a heater (not shown) to generate warm water, and pressurizes the warm water as washing water. As shown in FIG. 3, the warm water supply device 62 is disposed at a position directly below the cassette tank 61. Further, the end of the washing water hose 52 (the end opposite to the side connected to the adapter 10) is connected to the discharge port of the washing water provided in the warm water supply device 62. Thereby, the washing water sprayed from the warm water supply device 62 flows through the washing water hose 52, and finally is ejected inside the diaper P, specifically, in the space between the inter-strand portion of the user and the receptacle 10. .

Moreover, the warm water supply device 62 of the present embodiment can adjust the supply amount of the washing water. For example, the supply amount can be appropriately changed depending on the type of the excrement D and the elapsed time from the start of the washing.

The excrement receiving container 20 is an example of a waste storage body, and is a hollow container that accommodates the excrement D and the washing water that are sucked by the suction hose 51. The excrement container 20 of the present embodiment is a resin container formed of ABS, PP (polypropylene resin) or PVC (polyvinyl chloride), and is formed into a rectangular parallelepiped shape as shown in Fig. 4 . The excrement container 20 is generally utilized in a state of being housed in the box unit 35. Further, in the state in which the excrement container 20 is housed in the tank unit 35, the internal space of the excrement container 20 and the internal space of the tank unit 35 (strictly speaking, the tank unit 35 is located in the excrement container 20) The space on the outside is connected.

Specifically, as shown in FIGS. 3 and 4, the excrement container 20 has an upper wall (hereinafter referred to as a container upper wall 21). Further, in the upper wall 21 of the container, an exhaust port 22 composed of a rectangular opening is formed. In the state in which the excrement container 20 is housed in the tank unit 35, the exhaust port 22 is located at the end portion on the deep side in the depth direction in the container upper wall 21 as shown in Fig. 6 . As described above, since the excrement container 20 is provided with the exhaust port 22, the internal space of the excrement container 20 communicates with the internal space of the tank unit 35.

If the fan 41 is actuated to suck the air in the tank unit 35 while the excrement container 20 is being housed in the tank unit 35, the air in the excrement trap 20 is discharged from the exhaust port 22 and the tank. The air within unit 35 is drawn together by fan 41. As a result, the inside of the excrement container 20 is decompressed.

Further, as shown in Figs. 3 and 6, the container upper wall 21 is provided with a dust removing and deodorizing filter 23 at a position covering the exhaust port 22. The dust removal and deodorizing filter 23 is a rectangular sheet filter having a size larger than the exhaust port 22. When the air in the excrement container 20 passes through the exhaust port 22, the moisture in the air (strictly speaking, the mist from the excrement D and the washing water) is captured by the dust removing and deodorizing filter 23. In the present embodiment, the exhaust port 22 is covered by the dust removing and deodorizing filter 23 as described above. However, the exhaust port 22 may be opened without providing the dust removing and deodorizing filter 23.

Further, in the container upper wall 21, an end portion of the container upper wall 21 opposite to the end portion on which the exhaust port 22 is formed is provided with a substantially elongated through hole (hereinafter referred to as a suction port 24). The suction port 24 is formed by sucking the excrement D and the washing water into the excrement container 20. Further, in the suction port 24, as shown in Fig. 3, the end portion of the suction hose 51 (the end portion opposite to the side connected to the adapter 10) enters.

More specifically, the end portion of the suction hose 51 passes through the nozzle insertion hole 32a formed in the first lid portion 32, and is fitted into the inside of the cylindrical projection portion 32b which is mounted on the inner surface of the first lid portion 32. Here, the nozzle insertion hole 32a is in the state in which the excrement container 20 is housed in the tank unit 35, and the first lid portion 32 is closed, as shown in Fig. 7, is located at the suction port 24 of the excrement container 20. Directly above. Further, as shown in the figure, the end portion of the suction hose 51 inserted into the nozzle insertion hole 32a enters the suction port 24 and reaches the excrement container 20. Fig. 7 is a view showing a state in which the first lid portion 32 is closed and the end portion of the suction hose 51 enters the suction port 24.

As described above, in the present embodiment, the opening and closing operation of the first lid portion 32 allows the insertion and removal of the suction hose 51 for the excrement container 20 to be easily performed. Further, according to the above configuration, when the end portion of the suction hose 51 is pulled out from the excrement container 20, excessive force is not applied to the end portion of the hose. As a result, it is possible to avoid a situation in which the end portion of the hose is pulled out due to an excessive force applied to the end portion of the hose so that the excrement D is scattered from the opening of the end portion of the hose to contaminate the tank unit 35.

Further, in a state in which the first lid portion 32 is closed, the front end flange portion of the cylindrical projection portion 32b in which the end portion of the suction hose 51 is fitted is in close contact with the container upper wall 21 (more specifically, the suction port 24) Edge). Thereby, the airtightness of the excrement container 20 is secured, and the odor in the container can be prevented from leaking from the suction port 24 to the outside of the excrement suction device 1.

Further, when the first lid portion 32 is closed and the end portion of the suction hose 51 reaches the inside of the excrement container 20, if the fan 41 sucks the air in the tank unit 35, the inside of the excrement container 20 is decompressed. At this time, if the excrement D is carried on the adapter 10, the excrement D is sucked and moved into the excrement container 20 in the suction hose 51. When the washing water supply unit 60 is supplied with the washing water into the diaper P, the washing water is also sucked into the excrement collecting container 20 via the suction hose 51.

As will be strictly explained, if the sucked excrement D and the washing water are opened to the front end of the end portion of the suction hose 51 in the excrement container 20, the excrement container 20 may fall due to its own weight and Continue to accumulate in the container. On the other hand, the air sucked together with the excrement D and the washing water is separated from the excrement D and the washing water in the excrement container 20, and is discharged from the exhaust port 22 of the upper wall 21 of the container to the excrement. The container 20 is taken in by the fan 41 in addition to the container 20.

The stage in which the excrement container 20 has accumulated a certain amount or more of excrement and washing water inside is discharged from the tank unit 35. That is, the excrement container 20 is detachable from the box unit 35. More specifically, by opening the first cover portion 32 in the closed state, the end portion of the suction hose 51 is detached from the excrement container 20, and the opening at the upper end of the box unit 35 is opened. Then, when the handle 20a of the excrement container 20 is lifted while lifting the excrement container 20 upward, the excrement container 20 is removed from the box unit 35.

<<Detailed Structure of Excretion Container>> The structure of the excrement container 20 will be described in more detail with reference to Figs. 3, 4, 6, 8 and 9. Fig. 8 is a view showing the internal structure of the excrement container 20, and shows the excrement container 20 cut by the A-A plane in Fig. 2 . Fig. 9 is a view showing the flow of air in the excrement suction device 1, and is an enlarged view of the periphery of the excrement container 20 of Fig. 3. Further, the gas return hose 53 is not originally present in the cross section shown in Fig. 9, but for convenience of explanation, the gas return hose 53 is shown by a broken line in the same figure.

The excrement container 20 has an upper wall (container upper wall 21) provided with a suction port 24 and an exhaust port 22. The suction port 24 and the exhaust port 22 are attached to the end portions of the container upper wall 21 on the opposite sides. Further, in a state in which the excrement container 20 is housed in the tank unit 35, as can be seen from Fig. 3 and Fig. 6, the intake port 36 of the tank unit 35 is located closer to the suction port 24 than the exhaust port 22. Stay away from the location. More specifically, in the state in which the excrement container 20 is housed in the tank unit 35, the end portion of the upper wall 21 of the container having the deep side in the depth direction is located at the end portion, and the front side is located at the front side. The end has a suction port 24 located there. Further, as described above, among the side walls of the tank unit 35, a rectangular suction port 36 is formed on the side wall of the end portion on the deep side among the depth directions.

According to the positional relationship between the exhaust port 22, the suction port 24, and the intake port 36 described above, the air entering the waste container 20 is discharged from the exhaust port 22 to the outside of the container and is sucked from the air inlet 36 to the fan. The passage (hereinafter referred to as the wind path) passed during the period of 41 will be sufficiently ensured. As a result, the air in the excrement container 20 can be well separated from the washing water by the excrement D.

The internal structure of the excrement container 20 will be described below. In the internal space of the excrement container 20, as shown in Figs. 3, 8 and 9, a partition plate 25 and a spoiler 26 are provided.

The partition plate 25 is a plate-like member that is provided to partition the internal space of the excrement container 20. As shown in Fig. 8, the partition plate 25 is located between the exhaust port 22 and the suction port 24 in the internal space of the excrement container 20. Specifically, the partition plate 25 is disposed at a substantially central portion of the internal space of the excrement container 20 in the depth direction. Therefore, the exhaust port 22 and the suction port 24 are located on the opposite sides of each other as viewed from the partition plate 25.

In addition, in the internal space of the excrement container 20, the area which is located closer to the suction port 24 than the partition plate 25 is referred to as a "first storage area", and is located closer to the exhaust than the partition plate 25. The area on the side of the port 22 is referred to as a "second storage area".

The partition plate 25 is vertically erected from the bottom surface of the excrement container 20 as shown in Fig. 8. By providing the partitioning plate 25, the solid waste is accumulated in the first storage area, and on the other hand, the liquid excrement and the washing water are accumulated in the second storage area to separate the solid waste. . Further, by providing the partitioning plate 25, the undulation of the liquid material accumulated in the second storage region can be suppressed. By this effect, the detection accuracy of the detector 38 can be improved, and as a result, the operation of the excrement suction device 1 can be stabilized.

Further, the upper end of the partitioning plate 25 is located slightly lower than the lower surface of the upper wall 21 of the container. That is, as shown in Figs. 3 and 9, a gap 27 is formed between the upper end of the partitioning plate 25 and the upper wall 21 of the container. The gap 27 is located midway between the air passages, and the air in the waste collection container 20 can pass. That is, the air sucked into the excrement receiving container 20 together with the excrement D and the washing water is moved from the first storage area to the second storage in the excrement receiving container 20 as shown in FIG. Through the gap 27, the area passes.

Further, in the present embodiment, the gap 27 is formed in a state where the entire upper end of the partitioning plate 25 is separated from the lower surface of the upper wall 21 of the container, but the present invention is not limited thereto. That is, the gap 27 may also be formed between the upper end of the partitioning plate 25 and the lower surface of the upper wall 21 of the container. For example, a portion of the upper end of the partitioning plate 25 may be cut, the cutout portion may be separated from the lower surface of the upper wall 21 of the container, and the other portion may abut the lower surface of the upper wall 21 of the container. In this case, a gap 27 is formed between the cutout portion of the partitioning plate 25 and the lower surface of the upper wall 21 of the container.

Further, as shown in Fig. 8, the lower end portion of the partitioning plate 25 is provided with a water passing hole 25a. The water-passing hole 25a is formed by dividing a central portion of the lower end of the partition plate 25 in the lateral direction of the excrement container 20 into a substantially rectangular shape. By forming the one water passing hole 25a, the liquid material and the washing water accumulated in the excrement D in the first storage area will pass through the water passing hole 25a in the inner space of the excrement receiving container 20. Moving to the second storage area and accumulating in the second storage area.

The spoiler 26 corresponds to a flow path changing member which is a plate-shaped member which is provided at a position downstream of the partition plate 25 among the air passages formed in the internal space of the excrement container 20 . More specifically, the spoiler 26 is disposed in the internal space of the excrement receptacle 20 in the space between the partition plate 25 and the exhaust port 22 (ie, the second storage area). 27 opposite positions. Further, the spoiler 26 extends from the lower surface of the upper wall 21 of the container as shown in Fig. 8, and is inclined with respect to the height direction of the excrement container 20. More precisely, the spoiler 26 is inclined away from the partition plate 25 as it approaches the lower end.

In this way, the air passing through the gap 27 is made to contact the spoiler 26 to ensure that the air flow path is long. To be clear, the air in the waste collection container 20, as shown in Fig. 9, is moved to the spoiler 26 and then along the spoiler immediately after moving from the first storage area to the second storage area through the gap 27. 26 flows. The air flowing along the spoiler 26 is moved to the deep side of the excrement container 20 at the lower end of the spoiler 26 and then moved upward, and finally discharged to the outside of the excrement container 20 via the exhaust port 22. By providing the spoiler 26 as shown above, the moving distance of the air in the excrement receptacle 20 can be made longer.

As described above, in the present embodiment, the air sucked into the excrement container 20 together with the excrement D and the washing water moves through the internal space of the excrement container 20 (especially in the internal space). The upper portion thereof is discharged to the outside of the excrement container 20 via the exhaust port 22. Here, in the case where the air moves in the excrement container 20, the moving speed (flow rate) of the air becomes slower than in the case where the air moves in a general piping or a hose. Thereby, it is easier to separate the air from the excrement D and the washing water in the excrement container 20.

Further, the air that has escaped from the exhaust port 22 to the outside of the excrement receiving container 20 moves in the tank unit 35 and moves toward the intake port 36. After that, the air passes through the suction filter 37 in the tank unit 35, moves from the inside of the tank unit 35 to the fan casing 43 through the intake port 36 and the communication hole 43a, and is sucked into the fan casing 43 by the fan 41. In the present embodiment, the exhaust port 22 of the excrement container 20 and the air inlet port 36 of the tank unit 35 are interposed therebetween with a space of a portion of the tank unit 35 therebetween. In other words, in the present embodiment, the exhaust port 22 and the intake port 36 are not directly connected, and a duct or a pipe connecting the exhaust port 22 and the intake port 36 is not provided. This feature is a feature of the present embodiment and is an improvement of the excrement suction device 1 from the prior device.

More specifically, in the conventional apparatus, the exhaust port 22 of the excrement container 20 is directly connected to the air inlet 36 of the tank unit 35, or is connected via a duct or a pipe or the like. According to this configuration, the pressure loss when the air in the excrement container 20 is sucked becomes large. On the other hand, it is necessary to ensure the necessary attraction of attracting excrement and washing water, and therefore, a larger fan is used in the prior device. However, if the fan in the prior device is activated, the inter-strand portion of the user abutted by the adapter 10 will have a large attractive force, which will put a burden on the user's body. Further, in the case where the excrement suction device is operated, the heater of the warm water supply device 62 is activated in addition to the above-described fan, but if the fan and the heater are simultaneously activated in the previous device, they are generally supplied to the home. The power supply is not available, so it is the form of starting the heater and then starting the fan after a certain period of time. That is, in the prior device, it is difficult to immediately start the fan based on the limitation of the supplied electric power, and a time lag occurs between the user performing the excretion behavior and even when the excrement is attracted. Further, in the prior art, as described above, in order to operate the larger type of fan, the heat of the fan is also generated more frequently, and it is necessary to provide a heat sink (cooling mechanism) for removing the fan. In the case where a heat sink is provided, the former device becomes a large size correspondingly, and this poses a problem in terms of convenience in handling the device and the like.

For the above reasons, in the present embodiment, the fan 41 which is smaller than the user of the previous device is used. Further, in the present embodiment, as described above, a space is provided between the exhaust port 22 of the excrement receptacle 20 and the intake port 36 of the tank unit 35. Thereby, the pressure loss at the time of sucking the air in the excrement container 20 is alleviated, and as a result, even if the fan 41 is downsized, the air in the excrement container 20 can be appropriately sucked and the excretion is good. The ground is transferred to the excrement container 20.

Further, since a space is provided between the exhaust port 22 and the intake port 36, the air that has flowed out of the exhaust port 22 to the outside of the excrement trap 20 is temporarily released to the above space and then passes through the intake port. 36 is attracted by the fan 41. Thereby, when the fan 41 sucks the air in the excrement container 20, the moisture (the mist from the excrement D and the washing water) and the bacteria in the excrement D will be attracted together with the air. The contamination of the fan 41 or the gas return hose 53 or the like is suppressed.

In addition, as described above, the air that has been discharged to the excrement container 20 is temporarily released into the tank unit 35. Therefore, even if the air is mixed with the bacteria and the like, the air is discharged to the excrement container 20. Water, bacteria, and the like can still be contained in the tank unit 35 in advance. In other words, the present embodiment can suppress the expansion of the contaminated space.

Further, in the present embodiment, by arranging the respective portions of the excrement suction device 1 in the layout shown in Figs. 3 and 9, the excrement suction device 1 as a whole can be simplified and simplified, and the air can be taken. The pressure loss when flowing in the device is suppressed to be small. Thereby, the load at the time of inhalation of the fan 41 becomes small, and the magnitude of the output (power consumption) of the fan 41 is also suppressed. Further, since the output of the fan 41 is suppressed, an accessory device (for example, a heat sink) for removing the heat of the fan 41 is not required.

<<Other Embodiments>> In the above-described embodiment, an example of the configuration of the excrement suction device of the present invention will be described. However, the above embodiments are merely examples, and other embodiments are also conceivable. For example, in the above-described embodiment, the box unit 35 as the box portion, the excrement container 20, and the fan 41 as the suction unit are housed in one casing 31. However, it is not limited thereto, and the excrement container 20 and the box unit 35 may be housed in the outer casing 31, and on the other hand, the fan 41 is disposed outside the outer casing 31.

Further, in the above-described embodiment, the case where the excrement suction device of the present invention is sucked by sucking the excrement discharged by the user in the lying state is described as an example, but the present invention is not limited thereto. For example, the excrement suction device of the present invention can be used to attract the excrement of a person discharged from a non-washing type simple toilet provided in a disaster area.

Further, in the above-described embodiment, the air sucked together with the excrement at the time of sucking the excrement is returned to the inside of the diaper P, but it is not limited thereto, and the air sucked together with the excrement may be brought from the inside of the apparatus to the atmosphere. release.

Further, in the above-described embodiment, the excrement container 20 including the resin cans which are substantially rectangular parallelepiped is used as the excrement container for accommodating the excreted matter and the warm water, but the excrement container 20 is not limited thereto. For example, a bag body, a tubular body, or other device having a space in which excrement or the like is accommodated may be used as the excrement container.
