DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing device for an animal rack, and more particularly, to a washing pan for catching dirt falling from an animal accommodating place and flushing the received dirt with falling washing water. The present invention relates to a water washing device for an animal rack, which is provided below a storage location and is provided with a water supply container at an upstream end of the washing pan, which supplies washing water in the container to the washing pan by tilting.

[0002]

2. Description of the Related Art Conventionally, in this type of water washing apparatus for animal racks, as shown in FIG. 5, a water supply container 5 arranged at an upstream end of a washing pan 3 is washed with water as shown by a dashed line in the figure. The washing water W in the pan 3 is tilted in the same direction as the washing water flowing downward (to the left in the figure), and the washing water W in the container is directly supplied onto the washing pan 3 in such a manner that the washing water W is simply allowed to flow out of the container 5 and fall. Was.

[0003]

However, in this type of flushing apparatus, the flushing water W is temporarily accumulated in the water supply container 5 so that the flushing water W flowing down on the flushing pan 3 has an appropriate momentum. A water supply mode is adopted in which the washing water W in the container is caused to flow out onto the washing pan 3 in a short time by the tilting of the container. In the above-mentioned conventional device in which the water is directly flown down onto the washing pan 3 in the same direction as the downward direction,
Although there is momentum toward the downstream side of the washing pan 3, the washing water W
Is supplied onto the washing pan 3 in a greatly disturbed state,
The flowing down washing water W traveling on the washing pan 3 has a non-uniform and uneven distribution of the flow velocity and the distribution of the water film thickness. There was a problem that washing residues easily occur.

In order to cope with this problem, the washing water W flowing out of the water supply container 5 toward the downstream side of the washing pan 3 is once received, and the received washing water W is guided onto the washing pan 3 while being guided. An appropriate guide structure such as an inclined guide plate may be provided between the water supply container 5 and the washing pan 3. In this case, there is a problem that the size of the apparatus is increased.

[0005] In view of the above circumstances, the main problem of the present invention is to avoid the increase in the size of the device by rational improvement,
An advantage of the present invention is that the supply of the washing water from the water supply container to the washing pan due to the tilting is less disturbed, and the flushing function is improved.

[0006]

Means for Solving the Problems [Invention of claim 1] In the invention of claim 1, the water supply container is tilted in a direction opposite to the downward flow of the wash water in the washing pan to discharge the wash water in the container. The outflow washing water (that is, the washing water flowing out in a direction opposite to the downflow of the washing water of the washing pan) is received by the vertical guide plate disposed in the vicinity of the washing water outflow side of the water supply container in a vertical position. Subsequently, the received washing water is caused to flow down along the surface of the vertical guide plate. Then, the washing water flowing down along the plate surface of the vertical guide plate is changed in the downstream direction of the flushing pan and supplied to the flushing pan during the transition from the vertical guide plate to the flushing pan.

In other words, in this supply mode, the washing water flowing out of the water supply container due to the tilting of the container is guided along the plate surface of the vertical guide plate and supplied onto the washing pan. The washing water discharged from the water supply container in the opposite direction to the washing water flowing down in the washing pan is turned in a direction utilizing the centrifugal effect in a direction along the washing water flowing down the washing pan (downstream of the washing pan). Since it is supplied onto the washing pan, the washing water from the water supply container is less turbulent compared to the above-described conventional apparatus, while having appropriate momentum toward the downstream side of the washing pan, and The washing water that can be supplied to the washing pan in a uniform state in the width direction of the washing pan can be supplied. As It can effectively improve the wash function for dirt on washing pan.

[0008] Further, as an apparatus structure, a vertical guide plate is provided at a location near the washing water outflow side of the water supply container, and the washing water received by the vertical guide plate is turned to the downstream side of the washing pan. In order to adopt the device structure using the space under the water supply container in the space for leading to the washing pan, the space is taken between the washing pan and the water supply container in the above-mentioned conventional device, and an inclined guide plate and the like are provided in this part. As compared with the case where an appropriate guide structure is additionally provided, the flushing function can be improved while avoiding an increase in the size of the apparatus.

Further , the vertical guide plate is formed into a curved plate shape which is gradually inclined toward the lower side and is continuous with the washing pan at the lowermost portion, so that the vertical guide plate has a vertical posture. The outflow washing water from the water supply container received on the surface is guided along the above-mentioned curved shape smoothly, and while effectively exerting the centrifugal effect, the washing water is changed in the downstream direction of the washing pan. The washing water can be supplied to the washing pan in a uniform state with less turbulence and the washing function can be more effectively improved.

[Invention according to claim 2] In the invention according to claim 2, the animal storage location and the washing pan are connected.
By providing a plurality of pairs in the vertical direction,
The water supply container and the vertical guide for each of the rinsing pans
By arranging a set with a board separately, multiple stages of flushing
The effect of the invention of claim 1 for each of the
Is obtained.

[0011] According to the third aspect of the present invention, the straightening plate facing the falling washing water is provided at an intermediate position in the washing water path from the vertical guide plate to the washing pan. By forming a rectifying gap flow path between the plate tip of the rectifying plate and the plate surface of the vertical guide plate, the washing water is leveled in the passage of the gap flow path so as to level the washing water. The water can be rectified, so that the rinsing pan is less disturbed, and the rinsing water can be supplied in a more effectively uniform state in the width direction of the rinsing pan, thereby improving the rinsing function. More effectively achieved.

Since the current plate is provided by utilizing the space below the water supply container, the size of the device is not increased by the additional equipment of the current plate.

[0013] In the invention according to the fourth aspect, the above-mentioned current plate is formed in a structure in which the gap width of the gap flow path becomes gradually smaller toward the downstream side in the downflow direction of the washing water. Thereby, the washing water leveling function in the passage process of the gap flow path can be enhanced, and the passage itself of the gap flow path can be smoothed. Therefore, the improvement of the washing function can be more effectively achieved.

[0014]

1 and 2 show an animal rack used for breeding laboratory animals, etc., in which a plurality of cage housing portions 2 for housing animal cages 1 arranged side by side are formed in a vertical direction. Each of the cage housing sections 2 of each stage receives dirt falling from each cage 1 and is provided with a washing pan 3 for washing the received dirt with the washing water W. A drain duct 4 is provided to collect the flushing waste discharged from the washing pan 3 together with the washing water W and guide it to a predetermined discharge location.

At the lateral end of the rack opposite to the side where the drainage duct 4 is provided, water supply containers 5 for separately supplying the wash water W to the washing pans 3 of each stage are arranged vertically one above the other. The container 5 has a container width d substantially equal to the width of the washing pan 3, and the washing water W supplied into the container from the water supply channel 7 via the electromagnetic valve 6.
When the water reaches a certain amount, it moves from the water storage posture shown by the solid line in the figure to the inclination posture shown by the dashed line in the figure around the horizontal axis P due to the movement of the center of gravity of the container accompanying the water supply (ie, the principle of lion threat). ), The washing water W in the container is supplied to the flushing pan 3 by outflow, and after the outflow, when the supply of water is stopped by closing the solenoid valve 6, the apparatus automatically returns from the inclined posture to the initial water storage posture.

In the figure, reference numeral 8a denotes a stopper which comes into contact with the water supply container 5 when the water supply container 5 is tilted to the inclined position and stops the water supply container 5 in the above-mentioned inclined position. And a stopper for stopping the water supply container 5 in the water storage posture by contacting the water supply container 5 with the water supply container 5.

As shown in FIGS. 1 and 3, when the washing water W is supplied from the water supply container 5 to the washing pan 3 by the above-described tilting, the water supply container 5 faces in the direction opposite to the downward direction of the washing water flow in the washing pan 3. (That is, rightward in the figure), and in the vicinity of the washing water outflow side of the water supply container 5, the washing water W flowing out of the water supply container 5 due to the container inclination is placed on a plate in a vertical position. A vertical guide plate 9 is provided for receiving the cleaning water W along the plate surface.

The vertical guide plate 9 is formed in a curved plate shape in which the inclination becomes gentler toward the lower side and is connected to the washing pan 3 at the lowermost portion.

That is, the washing water W, which has flowed out of the water supply container 5 due to the tilting of the container, is guided along the plate surface of the vertical guide plate 9 and is smoothly supplied to the washing pan 3. The washing water W that has flowed out of the water supply container 5 in the direction opposite to the downward direction of the washing water flow in the washing pan 3 is changed in a direction utilizing the centrifugal effect in a direction along the downward direction of the washing water flow of the washing pan 3 to wash the washing water 3. , The washing water W flowing out of the water supply container 5 is less disturbed and uniform in the width direction of the washing pan 3, while having a sufficient momentum toward the downstream side of the washing pan 3. Is supplied to the washing pan 3 in a proper state, whereby the flowing down washing water W, which travels on the washing pan 3, is made uniform on the washing pan 3 with its velocity distribution and water thickness distribution being uniform and less disturbed. Wash off filth It is so as to increase the capacity.

In the figure, reference numeral 10 denotes a rectifying plate provided in a position facing the falling washing water W in the middle of the washing water path from the vertical guide plate 9 to the washing pan 3. The flowing down washing water W is passed through the gap flow passage 11 formed between the cleaning water W
The washing water W is supplied in a state where the washing water 3 is less disturbed and in a state where the washing water 3 is more effectively made uniform in the width direction. It is.

The leading end of the rectifying plate 10 is bent to the downstream side so that the width of the gap of the gap flow path 11 is gradually reduced toward the downstream side by this bent shape. The cleaning water leveling function is enhanced, and the passage of the clearance channel 11 itself is made smooth.

The above-mentioned vertical guide plate 9 and current plate 10
Have a plate width substantially the same as that of the washing pan 3, and the vertical guide plate 9 also serves as a side plate on one side of the rack.

[Another Embodiment] Next, another embodiment will be described. The specific shape of the water supply container 5 can be variously changed, and the tilting of the water supply container 5 may be performed by power instead of the one performed by the principle of the lion threat as in the above-described embodiment.

In the vertical guide plate 9, the portion of the plate surface in the vertical position for receiving the outflow washing water W from the water supply container 5 is not limited to the plate surface in the vertical position. It may be a plate surface with an inclined posture approaching.
