NL9401953A - Automatically cleaning pet basket - Google Patents

Abstract

The invention relates to an automatically cleaning pet basket comprising a cylindrical housing; a screen is secured in the housing, by means of which screen, during the cleaning phase, absorbent material which is present in the living space is separated into relatively coarse pieces which are to be separated out and relatively fine pieces, and to which screen a bin is attached, provided with an opening through which, during the cleaning phase, the relatively coarse pieces of the screen fall into the bin, while the relatively fine pieces which pass through the screen fall into a buffer chamber; the opening of the bin can be closed off by a flap which is connected to the screen. A storage vessel is also attached to the cylindrical housing, from which vessel absorbent material is introduced into the living area by means of a metering system during each cleaning phase. The packaging of the absorbent material is such that, when it is empty, it can be coupled to the discharge opening and then forms the bin.

Description

AUTOMATICALLY CLEANING PET BIN

The invention relates to an automatic cleaning pet litter according to the preamble of claim 1, a packaging of the absorbent material to be used in the automatic pet litter according to the preamble of claim 5, and a method for automatically cleaning a pet litter according to the preamble of claim 6.

Such devices are known from the literature, however the practical use of such litter boxes has been limited.

The drawback of the known litter boxes is the way in which the separated coarser parts are stored. In the known devices it has hitherto not been successful to have this storage take place in an odorless manner.

To overcome the above-mentioned drawback, the pet bowl is designed according to the feature of claim 1.

By closing the waste container with a valve connected to the sieve, a good odor barrier is obtained in a simple manner. The subsequent claims include preferred embodiments of the pet tray, whereby further improvements of the pet tray are achieved.

The invention will be explained below with reference to an exemplary embodiment.

IMPLEMENTATION EXAMPLE

The automatic pet box consists of (see drawing): A. cylindrical housing B. sieve C. buffer space still usable grit D. storage tank clean grit E waste container F. waste container valve G electrically driven rollers K sensor I. dosing room K. opening in lid L. lounge area M. absorption materialN drum rotation axis

At the bottom of a dwelling space (L) of a cylindrical housing (A), which is closed at both ends with a lid, and is further referred to as a drum, there is a layer of loose absorbent material (M), further referred to as grit. This material is intended to collect animal feces and prevent drum (A) from becoming smeared.

The drum can rotate about a rotation axis (N) by means of an electric drive (G).

Rotation of the drum leads to: 1. enveloping the excrement by grit 2. separating grit and excrement 3. opening and closing waste container (E) 4. dosing new grit

The living area (L) is accessible to small pets through an opening (K) on the front. The sensor (H) signals the presence or absence of an animal in the enclosure (L) in the drum (A).

Description of the operation of the pet bowl:

Sensor (H) detects the presence of an animal in the enclosure (L). System is given the status 'in use'. System wait for presence to end.

Sensor detects animal absence. System is given the status 'waiting'.

When the waiting time has expired, the cleaning cycle starts. The drum rotates ± 45 degrees back and forth, covering the excrement with grit.

The drum then continues to rotate, so that the grit with the excrement slides on a sieve (B). The drum stops or rotates so that the coarser parts of the grit are separated from the grit and the finer parts (still usable grit) have time to fall through the sieve. This grit is collected in a buffer space (C) for the still usable grit.

A waste container valve (F) opens due to gravity. A dosing space (I) of a storage vessel (D) fills with clean grit.

As it continues to rotate, feces and grit clinking over the sieve slide into the waste container (E).

When the drum is rotated even further, the flap (F) of the waste container closes again by gravity. The collected, still usable grit slides back through the sieve into the drum. The dosing space (I) of the storage vessel (D) empties into the drum.

The drum stops when it is back in the starting position and is ready for use again.

The waste container (E) can be designed as a separate container that can easily be taken out for cleaning.

The waste container can also be designed in such a way that it can be used as packaging for the sale of new grit. The user can then empty the packaging into the space for the new grit and then slide the empty packaging into the drum as a waste container. The packaging filled with waste can easily be disposed of with household waste.

Claims (6)

An automatic cleaning pet bowl comprising a single-cylinder housing (A) which is closed at both ends with a lid, at least one of the lids being provided with an opening (K), allowing a pet to occupy a living space (L) in the cylindrical housing during the use phase , and means (G) that enable the house to rotate about the axis of rotation (N) of the house during the cleaning phase, wherein a screen (B) is fixed in the house with which absorption material present in the accommodation space during the cleaning phase (M ) is separated into coarser, separated parts and finer parts, characterized in that a waste container (E) is attached to the cylindrical housing, provided with an opening through which the coarse parts of the sieve fall into the waste container during the cleaning phase and which opening can be closed by means of a the strainer connected valve (F). The automatic cleaning pet bowl according to claim 1, characterized in that the finer parts passed through the screen fall into a buffer space (C). An automatic cleaning pet bowl according to claim 2, characterized in that the valve (F) is provided with a rotary axis, such that the valve opens during the cleaning phase and subsequently closes as a result of the rotation of the cylinder-shaped housing. An automatic cleaning pet bowl according to claim 1, characterized in that a storage vessel (D) is attached to the cylindrical housing, from which absorption material is introduced into the accommodation space by means of a dosing system (I). 5. Packaging in which absorbent material is transported to an automatic cleaning pet container provided with a waste container (E), the pet container being provided with separating means (B), wherein separated parts fall out of the pet container into the waste container through a valve provided with a valve (F), characterized in that the empty package is formed such that it can be coupled to the discharge opening and then form the waste container. 6. Method for automatic cleaning of the absorption material (M) present in a accommodation space (L) of a pet box, which absorption material can be separated into coarser, separable parts and finer parts, wherein the separation takes place with a rotate cylindrical housing-connected sieve, characterized in that the cylindrical housing is rotated, the coarser parts falling into a waste container opened by the rotation of the housing and at the same time new absorption material is supplied.
