Description

The present invention relates to a biotoilet that transports pet urine to an organic waste treatment unit and decomposes the urine in a short time to prevent malodor from diffusing indoors, mainly for breeding dogs indoors. This is an automatic cleaning toilet for pets.

Conventionally, as shown in Patent Document 1, an automatic cleaning toilet for pets (for cats)
As a technical idea for automatically processing pet urine, European Patent Publication EP 721731 is disclosed. This patent is mainly for cats and is provided with a manure fork as a means for separating sand and excrement and a cat sand plate is disclosed. .

  The moving destination of the compost fork is provided with a container for collecting solid excreta provided to be openable and closable, separating sand and excrement, and collecting only solid excrement.

The container collecting the waste can be removed from the device so that it can sometimes be emptied.

The compost fork works when the urine is dried and solidified, and when the excrement is put in the container, the sand plate for cats is almost uniformed by sending it in the reverse direction with the compost fork, and when the sand is reduced, A person replenishes sand by the amount of decrease.

Such technology is marketed under the trade name Ritter Maid Mega.
European Patent Publication EP 154540 describes a small pet toilet such as a cat intended to be placed indoors. US Pat. No. 6,057,017 there is a movable rake above the basin, i.e. the basin, which moves the solid waste to the edge of the basin, where the solid waste is Falls into a rotating drum placed underneath. The drum thereby functions as a waste collection container, which contains some odor removing material. The drum can be removed from the device so that it can sometimes be emptied.

The technology disclosed above collects excrement in a container that collects the excrement temporarily in the container, which can reduce indoor odors. There was a problem of spreading into the room. In other words, it is not possible to completely prevent the odor from being diffused into the room, and it is necessary to discard the container for collecting excrement and to periodically clean and wash it.

JP-A-2005-124544 is disclosed as another technique for an automatic cleaning toilet for pets (for cats). Patent Document 3
In this toilet, when pets (cat) excrement into pellets made of organic waste treatment material instead of sand, droppings of feces are dropped to the lower part by rake, and the technology to decompose and extinguish cat excrement in the lower processing part is disclosed. ing.
However, if the upper pellet becomes dirty, a bad odor diffuses from the upper pellet into the room, as in the above-mentioned Patent Documents 1 and 2.

As a technique for an automatic cleaning toilet for pets (for cats, dogs, and small animal cages), International Publication No. WO2004-103069 is disclosed. Patent Document 4
The self-cleaning toilet for pets for cats discloses a technique for packaging so that odors do not spread by raked when urinating.
The automatic cleaning toilet for pets for dogs and small animal cages discloses a technique in which manure is taken with a toilet sheet and the toilet sheet is covered with a cover sheet and packaged.
However, the technique of the present invention does not diffuse bad odors in the room, but has a drawback of increasing the seat consumption.

Such a set container for collecting excrement is usually installed in an invisible place such as a corner of a room or a corridor, but if the breeder neglects to clean the set container for collecting excrement, feces, There was a problem that the bad smell of urine spread indoors and the living environment deteriorated.

  When pets are bred, they often generate odors. Countermeasures against these odors are made with commercially available deodorants and fragrances. However, since these methods are not unprecedented, the countermeasures have not been sufficient.

As described above, it takes a lot of time to clean and smells, so the biggest difficulty in raising pets is the following.
The present invention provides a device that reduces the labor of cleaning the toilet and does not diffuse malodors into the room even when the owner is away.
It must also reduce the economic burden.

Because aerobic fermentation microorganisms are cultivated in the boarding part on which pets board and excrete feces or urine, the organic waste treatment part that decomposes and eliminates manure excreted in the boarding part, and the organic waste treatment part The granule shape and pellet shape growth bed is housed, and equipped with a stirrer that stirs the growth bed inside the organic waste treatment unit, and the boarding unit carries at least excreted feces to the organic waste treatment unit And a sensor for detecting whether or not the pet is on the boarding part, and after detecting that the pet is on the boarding part, at least feces to the organic waste processing part by the transporting means Move to disassemble and eliminate feces.

According to the present invention, it is possible to move the urine to the organic waste treatment part that decomposes and eliminates the excreta excreted by the pet on the boarding part, and to decompose the urine in a short time, thereby eliminating the root of malodor, It is hygienic because it can prevent breeding. Moreover, even if manure is in the process of decomposition, the odor is removed from the air exhausted by the deodorizing function provided in the middle of the exhaust path, so that the indoor living environment is not deteriorated.

  Moreover, since a toilet seat is not used unlike the past, the economic burden is reduced.

Since the boarding board is a belt conveyor made of silicon sponge on the surface, the dog can feel the feel of a conventional toilet seat even for dogs that are pets. In addition to being able to change to the toilet of the invention, urine flows through the gap between the protrusions by embossing (projections) provided on the surface of the silicon, and the dog's feet are supported by the protrusions, so the urine is Because it is difficult to adhere to the back of the floor, the floor is hardly soiled.
In addition, because of the silicon sponge, not only is it difficult for human waste to adhere, but also cleaning is easy.

Since the boarding part can be detachably mounted above the organic waste treatment part, when the dirt is noticeable, the boarding part can be removed and washed.
In addition, since it is configured to be detachable from the agitation drive unit of the organic waste treatment unit, even when the granulated or pellet-shaped growth bed is deteriorated and replaced, the organic waste treatment unit is removed together with a new one. By attaching the container of the organic waste processing section, it is easy to exchange, and there is no worry of getting hands dirty or spreading the powder and pellets on the growing floor.

For odor countermeasures, air is introduced through the gap between the boarding sections, and the odor is induced by passing through the organic waste treatment section. After the odor source has passed, volatile vapor or spray of hypochlorous neutral water After the bad odor is decomposed and reacted by the fan, the non-brominated air is exhausted outside the automatic cleaning toilet by the fan, so that the living environment is not deteriorated.
Needless to say, the same effect can be obtained by decomposing the malodor by using ozone or other deodorizing agents.
In order to maintain the growth of aerobic degrading bacteria in the organic waste treatment department, before the odor source elapses, rather than spraying a deodorant or ozone that decomposes the odor, after the odor source has elapsed Although it is preferable, the same effect can be obtained in both cases of the decomposition effect of the exhausted odor.

For this reason, when the wing rotates, the flow of the internal flow changes every row.

The stirring blade 19 is preferably made of a material that absorbs stress by bending the blade when a load is applied. For this reason, if a very strong and hard material is used, the stirring motor 23 is burdened, which is not preferable. When the thickness of the tip of the blade is adjusted using Toray TPE 5557 as the molding material, a stirring blade having a preferable strength can be formed.

The organic waste treatment unit 9 has a growing bed made of sawdust and wood chips (not shown), and aerobic degrading bacteria are fixed on the growing bed in advance. Degradation is initiated by natural aerobic degrading bacteria without fixing them, but there is a difference in degradation rate,
The quality is stabilized by fixing EM bacteria and HIDM bacteria (Masaki Envic Co., Ltd.) having a high decomposition rate, and keeping the humidity at about 50% and sealing with a sheet material.

A heat insulating material 24 is provided around the organic waste treatment unit 9 and the bottom surface, and inside the belt unit 2, and the heat generated during the decomposition process is kept warm to accelerate the decomposition rate.
Further, a silicon rubber heater (not shown) is arranged on the bottom surface, and the heater is heated when the winter season or fermentation temperature does not rise.
The heater is provided with a thermocouple so that the temperature does not rise too much, and the temperature control is controlled, and the heater is controlled so as not to be heated to 80 ° C. or more by a thermistor for preventing overheating.

  Inside the toilet body 1, a sirocco fan 25 is arranged to flow air so that bad odors during the decomposition process do not go into the room, and deodorized air is exhausted from the exhaust port 6 to the exhaust port. For this reason, the air flow enters from the surface of the belt unit, passes through the organic waste treatment section, and is exhausted by the sirocco fan 25.

A deodorant mixing rod 27 is disposed below the deodorant tank 7, and the deodorant is supplied from the nozzle 28 attached to the deodorant tank 7.
