JPH09168346A - Washer for cage for rearing experimental animal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable automatic, efficient and perfect washing of rearing cages without requiring manual labor. SOLUTION: The cleaning chamber 3 is set on the base 1. The chamber is equipped inside with a table of draining boards 8 which can horizontally move at a prescribed speed. Two of cyclone jet nozzles are arranged at the upper and lower part each inside the chamber 3 so that the moving table 8 is interposed between them. Then, hot water, hot water containing a detergent and rinsing water are jetted in order through these nozzles 6, 7 at prescribed pressures for certain times.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for laboratory animal breeding boxes.

[0002]

2. Description of the Related Art Conventionally, a laboratory animal housing box is washed manually by rubbing it with a brush while sprinkling water with a hose to remove dirt.

However, in the case of manual work, even if one piece is washed, it is very tired, inefficient, and hygienic, which is not preferable. Moreover, even the feces and urine stones adhering to the corners of the box could not be washed off completely.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an experimental animal breeding box capable of efficiently and completely washing without manual labor. It is intended to provide a cleaning device for use.

[0005]

The gist of the present invention is to provide a cleaning chamber provided on the upper part of the base and a cage-shaped cage which can be moved horizontally at a predetermined speed in the cleaning chamber. From a moving table and a cyclone jet nozzle that is arranged above and below the cleaning chamber so as to sandwich the moving table, and sequentially ejects hot water or hot water containing detergent and rinsing water at a predetermined pressure for a predetermined time. It is in a cleaning device for laboratory animal breeding boxes.

Next, the operation of the present invention will be described. The cage-like transfer table on which the breeding box is placed is moved horizontally at a predetermined speed, and at the same time, 60 Kg / cm ^{2 is} supplied from the cyclone jet nozzles arranged above and below in the washing chamber.
At this pressure, hot water, or hot water containing a detergent and hot water for rinsing are sequentially ejected for cleaning.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.
This will be described with reference to the drawings. 1 is a partially cutaway front view of the whole, FIG. 2 is a partially cutaway side view of the whole, FIG. 3 is a front view of the base, FIG. 4 is a plan view of the base, and FIG. Is a front view of the upper chamber forming the cleaning chamber, FIG. 6 is a plan view of the upper chamber, and FIG.
8 is a front view of a lower chamber forming a cleaning chamber, FIG. 8 is a plan view thereof, FIG. 9 is a front view of a moving table, and FIG. 10 is a plan view thereof.

In the figure, 1 is a base, and a caster 2 is attached to the bottom. A cleaning chamber 3 is provided above the base 1, and is formed by an upper chamber 4 and a lower chamber 5. Further, the upper chamber 4 is constructed so that the front door 4a can be opened and closed, and in the present embodiment, it is constructed so as to slide in the vertical direction. The door 4a is provided with a peep window 4a '. Further, in the present embodiment, the door 4 is connected via a limit switch (not shown).
The cyclone jet nozzle, which will be described later, starts operating when a is closed, and stops operating when it opens.

The bottom of the lower chamber 5 is narrowed, and a drain port 5a is provided at the bottom. Cyclone jet nozzles 6 and 7 are arranged in the upper chamber 4 and the lower chamber 5 so as to sandwich a moving table described later.
Further, the cyclone jet nozzles 6 and 7 are preferably capable of appropriately adjusting the ejection angle, and are configured so that the ejection time can be set via a timer. A mechanism for supplying hot water alone, or hot water containing detergent and hot water for rinsing to the cyclone jet nozzles 6 and 7 is not shown.

Reference numeral 8 denotes a cage-like moving table. The moving table 8 is horizontally movably attached along a guide groove 9 provided at the lower end of the upper chamber 4, and is reciprocally moved by an appropriate driving mechanism. still,
In this embodiment, the operating rod 12 connected to the swinging rod 10 via the connecting rod 11 is connected to the moving table 8, and the moving rod 8 is moved by horizontal movement of the operating rod 12 by the swinging motion of the swinging rod 10. The table 8 is configured to reciprocate. Further, in the figure, 12 and 13 are universal joints, and 14 is a breeding box.

[0011]

EFFECTS OF THE INVENTION Since the present invention has the above-described structure and operation, it is possible to wash efficiently and hygienically without manual labor, and to wash 120 to 150 pieces per hour. It will be. Also, in the case of a small breeding box such as a rat or mouse breeding box, it is possible to wash two at the same time, which can reduce the labor and greatly improve the work efficiency. The cyclone jet nozzle blows hot water into the shape of a chaff with a strong pressure, so even things that adhere firmly to the corners of the box can be easily washed off, and can be thoroughly washed. is there.
