[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pet toilet used as a toilet for pets of cats and dogs (hereinafter, simply referred to as "pets"), for example.

[0002]

[Prior art]

 With the recent changes in the housing environment and the increasing popularity of high-end small pets, the number of pets kept indoors has increased. When pets are kept indoors, it is necessary to have a pet toilet in the room. For this reason, there is an increasing demand for pet toilets that can effectively suppress the odor of feces discharged by pets. Conventional pet toilets having the following configurations are widely used.

A conventional pet toilet is composed of a defecation chamber having an opening at the top and a defecation port at the bottom, and a storage chamber provided below the defecation chamber which is closed from the outside. The defecation chamber is filled with a water-absorbing member composed of a water-absorbing zeolite that can absorb feces, and sand that absorbs feces due to voids between particles.

When a pet discharges feces into the defecation chamber, the discharged feces are absorbed by the water absorbing member. The feces that cannot be completely absorbed by the water absorbing member flow down below the defecation chamber, flow down into the defecation port at the bottom of the defecation chamber, and are accumulated in the detention chamber. Since the storage chamber is closed from the outside, it is possible to prevent the odor of feces stored in the storage chamber from being released to the outside air.

[0005]

[Problems to be solved by the device]

 However, in the conventional pet toilet, most of the discharged feces are absorbed by the water absorbing member or adhere to the water absorbing member. Therefore, there is a problem that the odor of feces is released to the outside due to the vaporization of feces absorbed or attached to the water absorbing member of the defecation chamber.

The present invention has been made in order to solve the above-mentioned problems, and suppresses the release of odor of feces from the defecation room of a pet toilet, and further from the storage room to the outside. The purpose is to do.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a configuration of a pet toilet 1 (hereinafter, simply referred to as “toilet 1”) which is a first embodiment of a pet toilet according to the present invention. As shown in FIG. 1, the toilet 1 is composed of a defecation chamber 5 formed of an inner box 2 and a water repellent member 4, and a reservoir chamber 7 formed of an outer box 3 and an absorbent member 6. .

The outer peripheral portion of the inner box 2 is formed to have substantially the same shape as the inner peripheral portion of the outer box 3. Further, the depth of the outer case 3 is formed deeper than the depth of the inner case 2. Therefore, when the inner box 2 is fitted into the outer box 3, the inside of the outer box 3 is closed from the outside by the bottom of the inner box 2, and the reservoir chamber 7 is formed.

Further, the inner box 2 is opened above, and the bottom is formed so as to be inclined downward from the outer peripheral portion toward the central portion. This descent is provided to guide the flight downward. Here, the lowest part of the downward slope may be set at any position on the bottom. Furthermore, although the bottom portion is formed in a flat shape in the embodiment, it may be formed by providing a groove (not shown) or the like in order to keep the downward flow of feces constant. Further, in the vicinity of the center of the bottom of the inner box 2 (in the vicinity of the lowermost part of the descending slope), a plurality of defecation openings 8 are provided to allow the stool that has flowed out to the bottom to flow down into the storage chamber 7.

Further, the inner box 2 is filled with a water repellent member 4 formed of a water repellent material that repels water while absorbing almost no water. The water-repellent member 4 is composed of an aggregate of particles whose outer shape is, for example, several mm to several cm.

FIG. 2 is a diagram showing a detailed configuration of the water repellent member 4 of FIG. As shown in FIG. 2, the water repellent member 4 is formed by coating the surface of an arbitrary member 4a such as pebbles with a water repellent body 4b having water repellency such as silicon or ABS. ing. The reason why the surface is formed to have water repellency is to prevent the water repellent member 4 from absorbing and adhering stool, and to make the stool slide down quickly. The outer shape of the water-repellent member 4 is formed larger than the opening of the defecation port 8 so that the water-repellent member 4 does not drop from the defecation port 8 into the storage chamber 7.

Further, as shown in FIG. 1, an absorbing member 6 that absorbs feces is provided at the bottom of the storage chamber 7. FIG. 3 is a diagram showing a detailed configuration of the absorbing member 6 of FIG. As shown in FIG. 3, the surface of the absorbent member 6 is covered with the nonwoven fabric 6a. Further, the inner portion is composed of a mixture of a highly absorbent polymer 6b having water absorbency, a zeolite 6c, and a deodorizing pulp 6d having deodorizing property. Further, as shown in FIG. 3, a string 6e to be gripped when the absorbent member 6 is replaced is attached to one end of the nonwoven fabric 6a.

Next, the operation of the toilet 1 described above will be described. First, when a pet discharges feces into the defecation chamber 5, the discharged feces drip onto the water repellent member 4. Due to the water-repellent effect of the water-repellent member 4, this stool is hardly absorbed by the water-repellent member 4 and flows down to the bottom of the defecation chamber 5 without adhering. When the feces flow down to the bottom of the defecation chamber 5, the feces are guided to the defecation opening 8 provided at the bottom by the action of the downward slope formed at the bottom. As a result, the feces flow down from the defecation port 8 to the storage chamber 7.

The feces that have flown into the storage chamber 7 are absorbed by the absorbing member 6 provided at the bottom of the storage chamber 7. Since the feces stored in the storage chamber 7 as described above are blocked from the outside air, even if the feces are vaporized, the odor of the vaporized feces is not released to the outside air.

Further, since the water-repellent member 4 hardly absorbs feces and does not adhere thereto, almost no feces remain in the defecation chamber 5. Therefore, the odor of feces is hardly released from the defecation chamber 5 to the outside air.

FIG. 4 is a sectional view showing the configuration of a pet toilet 10 (hereinafter, simply referred to as “toilet 10”) which is a second embodiment of the pet toilet according to the present invention. As shown in FIG. 4, the toilet 10 is composed of a defecation chamber 5 formed of an inner box 12 and a water repellent member 4, and a reservoir chamber 7 formed of an outer box 13 and an absorbent member 16.

The bottom of the inner box 12 is formed such that one end (left side in the figure) of the outer peripheral portion is the lowermost part of the downward slope. A plurality of defecation openings 8 are provided at the bottom of the downward slope. Further, the outer box 13 is provided with a reservoir chamber 17 only at a position where feces flow down from the defecation port 8 (on the left side in the drawing), and the reservoir chamber 17 is provided with an absorbing member 16. The absorbing member 16 has the same structure as the absorbing member 6, but differs only in shape. That is, the absorbing member 16 is formed to have a minimum size for absorbing feces.

The toilet 10 can absorb the feces discharged into the defecation chamber 5 by the absorbing member 16 by the same operation as that of the toilet 1 described above. However, since the storage chamber 17 and the absorbing member 16 are formed smaller than the storage chamber 7 and the absorbing member 6 shown in FIG. 1, the toilet 10 is suitable for use with a small pet.

FIG. 5 is a sectional view showing the configuration of a pet toilet 20 (hereinafter, simply referred to as “toilet 20”) which is a third embodiment of the pet toilet according to the present invention. As shown in FIG. 5, the toilet 20 is provided with an upper cover 21 and a lower cover 29. The cross section of the outer peripheral portion of the upper cover 21 is formed in a substantially inverted concave shape, and the vibration isolator 28a is attached to this portion. A support plate 27 is provided at the bottom of the lower cover 29, and a vibration isolator 28b is attached to the support plate 27. The inner box 22 is supported by these vibration damping materials 28a and 28b.

A motor 32 for generating vibration is attached to a central portion on the lower surface side of the bottom of the inner box 22. A defecation port 8 is provided at the lowest part of the downward slope of the inner box 22. A reservoir chamber 23 is arranged below the defecation port 8. Further, the lower cover 29 is provided with an attachment / detachment port (not shown) so that the reservoir chamber 23 can be attached / detached from the outside. An absorbing member 26 is provided at the bottom of the storage chamber 23, and a deodorizing member 35 for suppressing the odor of feces is provided above the absorbing member 26.

A water repellent sheet 31 is arranged on the upper surface side of the bottom of the inner box 22 so as to cover almost the entire bottom of the inner box 22. Like the water repellent member 4 (FIG. 2) described above, at least the surface of the water repellent sheet 31 has water repellency, and is formed into a sheet shape such as cloth. An opening 31a is formed in a portion of the water repellent sheet 31 that overlaps the upper part of the defecation opening 8 of the inner box 22. The water repellent member 4 is filled on the upper portion of the water repellent sheet 31 as in the first and second embodiments (the water repellent member 4 is not shown in FIG. 5).

FIG. 6 is a sectional view showing in more detail the portion A of the inner box 22 of FIG. 5 in the figure. As shown in FIG. 6, a connecting portion 22a that connects the bottom portion and the side surface portion of the inner box 22 is formed in a thin shape. This is because the bottom of the inner box 22 can be easily vibrated by driving the motor 32.

Further, FIG. 7 is a sectional view showing a main part of a modified example of the toilet 20 of FIG. As shown in FIG. 7, a sensor 33 is attached to a part of the outer circumference of the upper cover 21. The sensor 33 is a sensor that monitors the entrance and exit of the pet into and from the defecation chamber 5, and is composed of a sensor lens 33a and a sensor element 33b. The sensor element 33b is an element including a light projecting unit that projects light and a light receiving unit that further receives reflected light of this light. The sensor lens 33a is a lens that condenses the light emitted from the light projecting portion of the sensor element 33b in order to irradiate the light in a predetermined range.

Next, the operation of the toilet 20 will be described with reference to FIGS. First, when power is supplied to the sensor 33, light is emitted from the light emitting portion of the sensor element 33b of the sensor 33. When the pet enters the defecation chamber 5, the light path of the light emitted from the sensor 33 is blocked by the pet, and the change in the reflected light is detected by the light receiving portion of the sensor element 33b. As a result, the presence of the pet is recognized and it is judged that the pet has entered the defecation room. When the pet discharges feces into the defecation chamber 5, the discharged feces flow down to the bottom of the defecation chamber 5 due to the water repellent action of the water repellent member 4 (not shown). That is, feces are dropped on the water repellent sheet 31 arranged at the bottom of the defecation chamber 5.

This stool slides down on the water repellent sheet 31 due to the downward slope formed at the bottom of the defecation chamber 5 and the water repellent action of the water repellent sheet 31, and is guided to the opening 31 a of the water repellent sheet 31. To be done. Further, the feces pass through the defecation opening 8 from this opening 31a and flow down into the storage chamber 23. The stool that has flowed into the storage chamber 23 is filtered by the deodorizing member 35, and the stool that has passed through the deodorizing member 35 is absorbed by the absorbing member 26. The odor of the stool is suppressed by passing through the deodorizing member 35.

When the pet having completed defecation exits the defecation chamber 5, the optical path of the sensor 33, which was blocked by the pet, is formed again, and the light receiving portion of the sensor element 33b detects the change in the reflected light again. As a result, it is determined that the pet has left the defecation room. Further, according to this information, power is supplied to the motor 32 after a predetermined time elapses (for example, several seconds), and the motor 32 is driven. The vibration generated by driving the motor 32 causes the bottom of the inner box 22 to slightly move. At this time, as shown in FIG. 6, since the connecting portion 22a between the bottom portion and the side surface portion of the inner box 22 is formed in a thin shape, the bottom portion of the inner box 22 vibrates sufficiently, but the side portion Does not vibrate much. Further, since the inner box 22 is connected to the upper cover 21 and the lower cover 29 by the vibration-proof materials 28a and 28b, the upper cover 21 and the lower cover 29 hardly vibrate.

The feces discharged into the defecation chamber 5 hardly remain in the defecation chamber 5 due to the water-repellent action of the water-repellent member 4 and the water-repellent sheet 31, but due to the surface tension of the feces, the feces are slightly discharged. It may remain without flowing down. However, when the above-mentioned vibration is applied to the defecation chamber 5, the surface tension generated in the feces is lost, and as a result, these feces are flowed down. As a result, almost all the discharged feces can be made to flow down to the storage chamber 23.

8 and 9 are views showing the configuration of a pet toilet 40 (hereinafter simply referred to as "toilet 40") which is a fourth embodiment of the pet toilet according to the present invention. Shows a sectional view, and FIG. 9 shows a plan view.

The toilet 40 has an upper cover 42 and a lower cover 43, and when the upper portion of the lower cover 43 is closed by the upper cover 42, a storage chamber 47 is formed inside the lower cover 43. . The upper cover 42 and the lower cover 43 are fixed by a plurality of screws 52 (FIG. 8 shows only one screw 52).

A reservoir box 56 having a substantially concave cross section is provided at a substantially central portion in the lower cover 43. The storage box 56 is for storing feces excreted by pets, and is provided so that it can be taken in and out from the outside (direction B in FIG. 9). The deodorizing member 35 for suppressing the odor of feces shown in the third embodiment is provided in the upper part of the storage box 56.

A defecation chamber 45 is formed in the upper cover 42. The defecation chamber 45 is composed of a defecation port 48 and a water repellent sheet 31 provided at the bottom, a support member 51, a water repellent member 44 provided above the support member 51, and the like. The defecation port 48 is formed at the lowermost part of the descending slope surface provided on the upper cover 42, and is opened in a substantially rectangular shape (FIG. 9). A large downward slope can be obtained by forming the defecation port 48 in the substantially central portion of the bottom portion like the toilet 40. The storage box 56 described above is arranged below the defecation port 48. The water repellent sheet 31 is the same as that shown in the third embodiment, and is arranged so as to cover almost the entire area of the downward slope surface of the upper cover 42. The opening 31 a of the water repellent sheet 31 is formed in a range including the upper part of the defecation port 48.

The support member 51 is a member formed in a mesh shape, and is stretched above the downward slope of the upper cover 42 substantially parallel to the installation surface of the toilet 40. Here, it is preferable that the mesh size of the support member 51 is coarse so that the stool does not remain in the mesh due to the surface tension of the stool or the like. Further, the supporting member 51 is hardened by ceramic processing or the like so that the supporting member 51 does not bend when a pet rides on it, and the surface thereof is subjected to a water repellent treatment.

The water-repellent member 44 is an aggregate of water-repellent pieces having a water-repellent surface, and is laid on the support member 51 so that the height from the support member 51 is about several cm. FIG. 10 is a perspective view showing in detail the specific shape of one water repellent member 44 (water repellent piece). As shown in FIG. 10, the water repellent member 44 is composed of a base body 44a and a plurality of protrusions 44b protruding at irregular heights from arbitrary positions on the surface of the base body 44a.

The water repellent member 44 having the protrusion 44b has the following effects. First, when the water repellent members 44 are adjacent to each other, the protrusions 44b are brought into contact with each other, so that an appropriate gap is formed between the water repellent members 44. This allows the stool to flow quickly. Secondly, since the protrusions 44b of the water repellent members 44 come into contact with each other so as to enter between the protrusions 44b of the adjacent water repellent members 44, relative slippage between the water repellent members 44 is unlikely to occur. Become. This prevents the limbs of the pet from being buried in the water repellent member 44 when the pet rides on the water repellent member 44.

The water-repellent member 44 is formed to have an outer size of about several mm. Therefore, the size of the mesh of the support member 51 described above may be any size so that the water-repellent member 44 does not drop from the mesh.

The description returns to FIG. In the upper cover 42, a ventilation chamber 55 is formed by the right side surface portion of the upper cover 42 in FIG. 8 and the portion where the lower right side cross section is formed in a substantially L shape. At the bottom of the ventilation chamber 55, a reservoir chamber 47 and a ventilation portion 42a that is opened to allow ventilation are formed. A fan 53 driven by a power source (not shown) is attached to the lower cover 43 side of the ventilation part 42a. The fan 53 blows air from the lower side to the upper side in the drawing.

Further, a drawer 57 is provided on the upper cover 42 side of the ventilation part 42a so as to be able to be taken in and out from the outside (direction C in FIG. 8). The bottom of the drawer 57 is opened in a predetermined shape so that it can be ventilated. Further, a deodorizing member 54 having a deodorizing effect is provided in the drawer 57. The deodorizing member 54 is formed by, for example, mixing non-woven fabric with activated carbon, a deodorizing material, or the like.

Furthermore, an opening 55 a that opens toward the defecation chamber 45 is formed in the upper part of the ventilation chamber 55. As a result, the reservoir chamber 47 and the defecation chamber 45 can be ventilated via the ventilation chamber 55.

Next, the operation of the toilet 40 will be described. When the pet discharges feces into the defecation chamber 45, the discharged feces flow down between the gaps of the water repellent member 44 due to the water repellent action of the water repellent member 44. The stool that has flowed down passes through the mesh of the support member 51 and drops on the water repellent sheet 31. This stool slides down on the water-repellent sheet 31 due to the water-repellent action of the water-repellent sheet 31 and the downward slope of the upper cover 42, passes through the defecation port 48 through the opening 31a and flows down into the reservoir chamber 47. The feces that have flown into the storage chamber 47 are dropped on the deodorizing member 35, filtered by the deodorizing member 35, and stored in the storage box 56. The odor of stool is suppressed by filtering the stool by the deodorizing member 35.

It should be noted that stool may remain in the voids of the water repellent member 44 due to the surface tension of the stool or the like. However, since animals such as dogs and cats have a habit of applying sand or the like to the stool portion after defecation, the water repellent member 44 is churned by this applying action and the surface tension of the remaining stool is lost. The stool is washed away.

The fan 53 is always driven by the supply of power. Therefore, the air in the reservoir chamber 47 flows toward the fan 53 side by the suction force of the fan 53. Further, this air flows from the ventilation portion 42a of the upper cover 42 into the ventilation chamber 55, and flows from the opening 55a toward the defecation chamber 45 side. Further, the air in the defecation chamber 45 flows into the reservoir chamber 47 from the defecation port 48 at the bottom of the upper cover 42 by the suction force of the fan 53. Therefore, the air in the toilet 40 is circulated between the defecation chamber 45, the reservoir chamber 47, and the ventilation chamber 55 by the fan 53, as shown by the arrow in FIG. Further, the circulating air passes through the deodorizing member 54 and is cleaned every cycle.

Even if the feces stored in the storage box 56 are filtered by the deodorizing member 35, the odor may remain in the storage chamber 47. Therefore, except for the case where the reservoir chamber 47 is completely closed, the odor of feces may be released from the reservoir chamber 47 to the outside air. In this case, by circulating the air as described above to clean it, it is possible to completely prevent the odor of feces from leaking from the storage chamber 47 to the outside.

Although the embodiments of the pet toilet according to the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. . For example, the water repellent member 4 may be made of a water repellent material without coating the water repellent body 4b. Further, the defecation opening 8 is not limited to a plurality and may be one.

The absorbent members 6, 16 and 26 may be made of, for example, a hydrophilic polymer or natural pulp, and the number is not limited to one, and a plurality of absorbent members may be installed. Furthermore, the absorbing members 6, 16 and 26 are formed so as to cover almost the entire bottom area of the storage chambers 7, 17 and 23, respectively, but are formed small only at the position where feces flow down from the defecation opening 8. May be. Although the toilet 20 shown in FIG. 5 includes both the absorbing member 26 and the deodorizing member 35, the toilet 20 may include only the absorbing member 26 or only the deodorizing member 35. Further, the absorbing member 26 or the deodorizing member 35 does not necessarily have to be provided.

The sensor 33 shown in FIG. 7 does not necessarily have to be provided. Further, it is not necessary to optically monitor the entrance and exit of the pet to the defecation chamber, and the presence of the pet may be detected by detecting the pressure acting on the defecation chamber 5 using, for example, a pressure sensor. good. In the embodiment, the sensor element 33b is composed of the light projecting portion and the light receiving portion, but, for example, the light projecting portion and the light receiving portion may be provided at the opposite positions on the outer peripheral portion of the upper cover 21, respectively.

As shown in FIG. 5, the motor 32 is applied as an example as means for giving vibration to the defecation chamber 5, but the invention is not limited to this, and any device capable of vibrating may be used. . Also, a switch or the like may be provided outside so that the pet caregiver can vibrate the defecation chamber 5 as necessary.

The water repellent member 44 may be formed in any shape and size. Therefore, although the base body 44a of the water repellent member 44 is formed in a substantially spherical shape (FIG. 10) in the embodiment, it is not limited to this and may be formed in a substantially elliptical shape. In addition, the shape, size, protrusion height, and number of projections 44b of the water repellent member 44 are not limited. For example, the base 44a may be formed in a substantially polyhedral shape like a tetrapot, and the protrusion 44b may be formed by protruding the apex of the base 44a.

In the embodiment, the air in the toilet 40 is circulated by the fan 53, but the fan 53 is mounted in the hollow area on the left side of the lower cover 43 in FIG. 8 to circulate the air without collecting the air. The air inside 47 may be blown outside through the deodorizing member 54. Although the deodorizing member 54 is provided on the exhaust side of the fan 53, it may be provided on either the intake side or the exhaust side of the fan 53 as long as it is on the air flow path of the fan 53.

Although the fan 53 is always driven, a power switch may be provided outside the toilet 40 so that the fan 53 can be driven as needed. Furthermore, it is possible to provide an odor detection sensor inside the storage chamber 47 or the like to automate the drive of the fan 53. The ventilation chamber 55 and the fan 53 are not limited to one place, but may be provided in a plurality of places.

[Effect of device]

 As described above, according to the pet toilet of claim 1, the discharged feces are hardly absorbed by the water repellent member filled in the defecation chamber, and do not adhere to the defecation chamber and flow down to the reservoir chamber. , Almost no stool remains in the defecation room. Therefore, it is possible to prevent the odor of feces from being released to the outside due to the vaporization of the feces remaining in the defecation chamber.
