Description

  The present invention relates to a circulation type automatic water dispenser for pets, which can supply drinking water of pets such as dogs and cats while automatically circulating them.

  When water is given to dogs and cats raised as pets, it is common to install a suitable drinking container, such as a water bowl that stores water, at a specified location, and to supply water to the pet from that container. Is. However, in such a way of giving water, the water in the drinking container may be left for a long time, which is not preferable for hygiene purposes.

  Therefore, in recent years, as shown in Patent Document 1 below, a circulation type automatic water supply device (watering device) has been proposed in which water is supplied while being automatically circulated.

  This automatic circulating water dispenser for pets includes a water bowl for storing water, an overflow portion provided above the water bowl, and an inclined water channel disposed from the overflow portion to the water bowl. The potable water is circulated by pumping up the water with a circulation pump and ejecting it from the overflowing part, allowing the water to naturally flow down along the inclined water channel and returning it to the water bowl. And it makes a pet drink the water which flows through an overflow part, an inclined channel, a water bowl, etc.

  In the conventional automatic circulation water dispenser for pets shown in Patent Document 1, the circulation pump is generally covered with a cover member or the like so as not to be visually recognized from the outside, and is hidden from the outside. It is difficult to see the water level directly. On the other hand, in order to reliably operate the circulation pump, that is, to surely pump water from the water bowl by the circulation pump, it is necessary to secure the water level in the water bowl.

  However, the user does not always accurately grasp the water level (minimum water level) required to operate the circulation pump, and if the water remains in the water bowl, the circulation pump may be obstructed. Some users have apologized for being able to work without any. For this reason, even if it is below the minimum water level, it may be mistaken that the amount of water is sufficient, and the operation of the water supply device may be continued without replenishing the water in the water bowl. In that case, problems such as a delay in water circulation may occur due to a lack of water. In this way, the user cannot recognize the necessity of water supply due to an unintentional drop in water level, and even if it recognizes a drop in water level, it may not immediately supply water, and there is a possibility that problems due to water shortage may occur. ing.

  The present invention has been made in view of the above problems, and can easily and reliably recognize the necessity of water supply due to an unintentional drop in water level, and can easily prevent water shortage in advance. The purpose is to provide an automatic water dispenser.

  In order to achieve the above object, the present invention has the following structure.

  According to the circulation type automatic water dispenser for pets of the invention [1], since the bottom surface of the pump chamber is formed lower than the bottom surface of the water storage chamber, when the water level in the pump chamber is low and water supply is required, There is almost no water remaining in the water storage chamber, and the user can easily and accurately grasp that water supply is necessary. For this reason, the user can accurately replenish water, prevent the occurrence of water shortage, and reliably prevent problems such as pump stoppage due to water shortage.

  According to the circulation type automatic water dispenser for pets of the invention [2], the user can easily and accurately grasp whether or not water supply is necessary by visually checking the remaining amount of water in the slow flow channel. The above effect can be obtained more reliably.

  According to the circulation type automatic water dispenser for pets of the invention [3], since water smoothly flows from the drainage zone to the pump chamber, the water can be circulated efficiently and smoothly.

  According to the circulation type automatic water dispenser for pets of the invention [4], since water flows more smoothly from the water storage chamber through the water passage to the pump chamber, the water can be circulated more efficiently and smoothly. .

Is the “right side”, and the lower side is “lower side” and the upper side is “upper side” in the front view of FIG.

  The water bowl 1 is made of, for example, a molded product of hard synthetic resin, and is integrally formed in a rising shape on a bottom wall 11 having a substantially circular shape in plan view, and an outer peripheral edge of the bottom wall 11, and And a peripheral wall 12 having a substantially annular shape in plan view. The water bowl 1 is opened upward, and the peripheral wall 12 is constituted by a double wall structure.

  As shown in FIGS. 4 and 5, a partition wall 15 that partitions the water bowl 1 forward and backward is integrally formed in a standing manner at a position slightly rearward of the intermediate portion in the front-rear direction on the inner surface of the water bowl 1. The partition wall 15 is formed so that the middle part in the left-right direction bulges forward, and the bulge part is configured as a semi-cylindrical columnar part 151.

  A portion in front of the partition wall 15 in the water bowl 1 is configured as a water storage chamber 20, and a portion in the rear of the partition wall 15 is configured as a pump chamber 23.

  Further, the bottom wall 11 of the water storage chamber 20 in the water bowl 1 is formed with a recessed portion 16 that is recessed downward in the vicinity of the partition wall 15. The recessed portion 16 is formed in a semicircular fan shape in plan view, a portion corresponding to the chord of the recessed portion 16 is adjacent to the partition wall 15, and a portion corresponding to the arc is the periphery of the water bowl 1. The wall 12 is arranged at a predetermined interval from the front half periphery of the wall 12 to the inside.

  As will be described later, in the water storage chamber 20 in the water bowl 1, a region corresponding to the recessed portion 16 is configured as a drainage zone 22, and other regions, that is, outside the drainage zone 22 in the water bowl 1. A region along the front half of the peripheral wall 12 is configured as a slow flow water channel 21.

  In the present embodiment, the recessed portion 16 does not constitute a part of the drainage zone 22 (water storage chamber 20), and the drainage zone 22 and the recessed portion 16 are regarded as different parts.

  In the present embodiment, the upper surface position of the bottom wall of the water storage chamber 20 (drainage zone 22) coincides with the upper end opening surface of the recessed portion 16.

  As shown in FIG. 5, a notch-shaped water passage 17 is formed on the right side (the other end side) of the lower end portion of the partition wall 15 so as to correspond to the recessed portion 16. In the water bowl 1, the pump chamber 23 and the drainage zone 22 are communicated with each other through the recessed portion 16 and the water inlet 17 so that the water can be passed therethrough, and the drinking water W in the drainage zone 22 is communicated with the recessed portion 16 and the water outlet. 17 is introduced into the pump chamber 23 through 17.

  In the present embodiment, a communication port that communicates between the front and rear of the partition wall 15 is not formed on the left side (one end side) of the lower end portion of the partition wall 15 as in the case of the water flow port 17. The drinking water W that has flowed in is introduced into the pump chamber 23 through only the water passage 17 on the right side of the lower end of the partition wall 15.

  Here, in this embodiment, the water channel is constituted by the recessed portion 16 and the water flow port 17. Furthermore, the one end side opening (upstream side opening) of the water passages 16 and 17 is constituted by the upper end opening of the recessed portion 16, and the other end side opening (downstream side opening) of the water passages 16 and 17 is the water inlet 17. It is constituted by. That is, one end side of the water passage 16 is opened at the bottom surface of the drainage zone 22 (water storage chamber 20), and the other end side is opened at the pump chamber 23.

  A filter installation step 161 is formed in the recess 16 along the inner peripheral wall surfaces before and after the recess. The upper end position of the stepped portion 161 is disposed below the upper end opening surface of the recessed portion 16 (the bottom surface of the drainage zone 22) by the thickness of the filter 25 described later.

  The filter 25 is formed in a semicircular fan shape corresponding to the shape of the recessed portion 16 in plan view. The filter 25 is fitted into the recessed portion 16 and is accommodated in an adapted state. In the state where the filter 25 is installed in this manner, the lower surface side of the filter 25 is supported by the stepped portion 161 in the recessed portion 16, whereby a space is provided between the lower surface of the filter 25 and the bottom surface of the recessed portion 16. Meanwhile, a water channel is formed. Furthermore, the upper surface of the filter 25 coincides with the upper end opening surface of the recessed portion 16 and is configured as the bottom surface of the drainage zone 22 (water storage chamber 20).

  In this configuration, the drinking water W in the drainage zone 22 passes through the water passages 16 and 17 through the filter 25 and is introduced into the pump chamber 23.

  In the present embodiment, all the drinking water W in the water storage chamber 20 (drainage zone 22) passes through the filter 25 and is fed into the pump chamber 23.

  In the present embodiment, the bottom surface of the pump chamber 23 is set at a position lower by about 24 mm to 39 mm than the bottom surface of the water storage chamber 20 (the upper surface of the filter 25). The bottom surface of the pump chamber 23 and the bottom surface of the recessed portion 16 are set to the same height (same level).

  As shown in FIG. 4, a pumping pump 26 is installed in the pump chamber 23 in the vicinity of the partition wall 15 at an intermediate position in the left-right direction. The water pump 26 is supported on the bottom surface of the pump chamber 23 with the discharge port 261 disposed upward. Further, the suction port (not shown) of the pumping pump 23 is opened near the bottom surface of the pump chamber 23. Thereby, the pumping pump 23 is configured such that drinking water W near the bottom surface is sucked from a suction port (not shown) and discharged upward from the discharge port 261. In the present embodiment, the height of the bottom surface of the pump chamber 23 is based on the surface (installation surface) on which the pump 26 is installed.

  As shown in FIG. 4, the peripheral wall 12 of the water bowl 1 is configured by a double wall structure as described above. The lower part of the inner wall 121 in the front half of the inner wall of the peripheral wall 12 is disposed so as to be inclined outward. The corner portion between the inner wall 121 and the bottom wall 11 on the front half circumference has an arcuate cross-sectional shape having a radius of curvature.

  In addition, the inner wall 121 of the front half circumference constitutes a side wall on the outer side (one side) of the slow flow water channel 21 described in detail later.

  As shown in FIGS. 1 to 4 and 6, the top funnel 3 disposed in the water bowl 1 is formed of, for example, a molded product of hard synthetic resin, and is a substantially dome that covers a region in the water bowl 1. It is formed in a shape.

  The outer peripheral wall of the top funnel 3 includes a drainage zone cover portion 32 that covers the upper portion of the drainage zone 22 and a pump chamber cover portion 33 that covers the upper portion of the pump chamber 23. In the present embodiment, a cover member is configured by the drainage zone cover portion 32 and / or the pump chamber cover portion 33.

  The peripheral edge of the second half of the top funnel 3, that is, the peripheral edge of the lower end of the pump chamber cover 33 is disposed corresponding to the rear edge of the peripheral wall 12 of the water bowl 1, that is, above the rear edge of the pump chamber 23. .

  Further, the peripheral edge of the front half of the top funnel 3, that is, the peripheral edge of the lower end of the drainage zone cover portion 32 extends downward so as to be disposed in the vicinity of the bottom surface of the water bowl 1. It arrange | positions corresponding to a front peripheral part. In the present embodiment, the portion (lower side) of the drainage zone cover portion 32 disposed in the water bowl 1 causes the water storage chamber 20 of the water bowl 1 to be connected to the slow flow channel 21 and the drainage zone 22. It is partitioned. In this way, a substantially semicircular arc (crescent-shaped) slow flow channel 21 is formed between the front half inner wall 121 of the peripheral wall 12 and the lower end of the drainage zone cover portion 32 in the water bowl 1. . In other words, the slow flow water channel 21 is formed in which the front half inner wall 121 of the peripheral wall 12 is one side (outside) side wall and the lower end of the drainage zone cover portion 32 is the other side (inside) side wall.

  Cutouts 321 are formed on both sides of the drainage zone cover 32 in the top funnel 3, and the slow flow channel 21 and the drainage zone 22 communicate with each other through the cutouts 321. Therefore, the potable water W in the slow flow channel 21 flows into the drainage zone 22 through the notch 321. Here, in this embodiment, the water outlet (water channel) is configured by the notch 321.

  In the present embodiment, a narrow gap is also formed between the lower end middle portion of the drainage zone cover portion 32 and the bottom wall 11 of the slow flow water channel 21. The flow channel 21 and the drainage zone 22 communicate with each other.

  Moreover, in this embodiment, the area | region corresponding to the slow flow water channel 21 in the bottom face of the water bowl 1 inclines gently downward from one end part (left end part) of the slow flow water channel 21 toward the other end part (right end part). It is formed on the inclined surface. Thereby, the drinking water W in the slow flow water channel 21 flows from one end side (upstream side) to the other end side (downstream side) of the slow flow water channel 21 by its own weight.

  On the other hand, in the region from the upper end portion on the outer peripheral surface of the top funnel 3 to the left side portion (one side portion) of the lower end edge portion of the drainage zone cover portion 32, the region is recessed downward to form a rapid water channel. 35 is formed.

  A dish-like (concave spherical) overflow portion 31 is formed in a region in the rapid water channel 35 at the upper end portion of the top funnel 3 by forming a recess in the region. A water supply pipe 36 extending vertically downward is integrally formed slightly behind the intermediate portion in the left-right direction on the bottom wall of the overflow portion 31 (see FIG. 4). The upper end of the water supply pipe 36 is opened at the bottom surface of the overflow portion 31 and is configured as a jet outlet 37.

  The lower end opening of the water supply pipe 36 is connected to the discharge port 261 of the pumping pump 26. Thereby, the drinking water W in the pump chamber 23 sucked up by the pumping pump 26 is supplied to the overflow portion 31 from the outlet 37 through the water supply pipe 36, overflows from the overflow portion 31, and flows out to the rapid water channel 35. It has come to be.

  In the present embodiment, the rapid water channel 35 constitutes an inclined water channel. The rapid water channel 35 is open to the one end side (left side) of the slow flow water channel 21 with the overflow portion 31 as the upper side and the lower end side. That is, the rapid water channel 35 is configured by an inclined surface that is inclined downward from the overflow portion 31 toward the slow water channel 21.

  Furthermore, the rapid water channel 35 has a steep steep slope in a part thereof. Specifically, the rapid water channel 35 is formed in a convex curved shape in which the gradient gradually increases from the upper end to the lower end, and the upper end portion is configured by a gentle gentle slope that is substantially horizontal, and the lower side portion. It is composed of steep slopes that are almost vertical. As a result, when the drinking water W introduced from the overflow portion 31 into the rapid flow channel 35 flows down the rapid flow channel 35 due to its own weight, it gradually increases in flow velocity and flows into one end side of the slow flow channel 21 vigorously. Yes.

  Here, in the present embodiment, the lower side portion of the rapid water channel 21 is formed with a steep slope. However, the present invention is not limited to this. good. Furthermore, in the present invention, the entire water channel of the rapid water channel 21 may be formed with a steep slope. In short, it is sufficient that a steep slope is formed in a part of the rapid water channel 35 so that the flow velocity of the drinking water W flowing through the rapid water channel 35 is faster than that of the slow water channel 21.

  In the present embodiment, an engagement protrusion (not shown) is formed on the peripheral edge of the lower end of the top funnel 3, and the protrusion is detachable in an engagement hole (not shown) in the peripheral wall 12 of the water bowl 1. By engaging, the top funnel 3 is detachably attached to the water bowl 1.

  In the circulating water dispenser for pets of the present embodiment, the circulating flow of the drinking water W by the pump chamber 23, the water supply pipe 36, the overflow portion 31, the rapid flow channel 35, the slow flow channel 21, the drainage zone 22, and the water channels 16 and 17. A road is formed. In the circulation channel, the drainage zone 22 and the pump chamber 23 are covered and closed by the cover portions 32 and 33 of the top funnel 3, whereas the slow flow channel 21, the overflow portion 31, the rapid flow The water channel 35 is not covered and the water surface is opened upward. In this embodiment, the flow path with the water surface opened upward in this way, specifically, the slow flow water channel 21, the overflow portion 31, and the rapid flow channel 35 are referred to as a water surface opening portion. Therefore, in this embodiment, the water surface opening part of the water storage chamber 20 is constituted by the slow flow water channel 21.

  Furthermore, in the present embodiment, the height of the bottom surface of the water surface opening portion (slow flow channel 21) of the water storage chamber 20 is based on the lowest position of the slow flow channel 21. For example, when the slow flow channel 21 is formed in a V-shaped cross section, the lower end (valley bottom) of the V groove is the height of the bottom surface. That is, in this invention, when it says that the bottom face of the pump chamber 23 is set low with respect to the bottom face of the water surface opening part (slow flow water channel 21), it is with respect to the lowest position of the water surface opening part (slow flow water channel 21). This means that the bottom of the pump chamber (pump installation surface) is set low.

  In the circulating water dispenser for pets of the present embodiment configured as described above, the drinking water W has a water level that is slightly lower than the maximum water level (maximum water level) indicated by the virtual line La as shown in FIG. Store in the water bowl 1. For reference, in the water dispenser of the present embodiment, when the drinking water W is injected into the water bowl 1 up to the maximum water level La, the amount of water becomes about 950 ml, and when the drinking water is injected up to the minimum water level La, the amount of water is reduced. About 350 ml. Needless to say, in the state where the potable water W is stored up to the minimum water level Lb, the suction port (not shown) of the pumping pump 26 is positioned below the water surface.

  In the present embodiment, a mark (memory) indicating the maximum water level La is described on the partition wall 15 so that the water level can be accurately confirmed visually.

  When the pumping pump 26 is driven with the drinking water W injected into the water bowl 1 in this way, the drinking water W in the pump chamber 23 is pumped up by the pumping pump 26 and ejected from the ejection port 37 through the water feeding pipe 36. And introduced into the overflow section 31. The drinking water W introduced into the overflow portion 31 overflows the overflow portion 31 and is introduced into the rapid water channel 35, and the drinking water W vigorously flows down the rapid water channel 35 to the left side (upstream side) of the slow flow channel 21. To be introduced. The drinking water W introduced into the slow flow channel 21 is gently moved from one end side (upstream side) to the gentle flow channel 21 by the slope of the slow flow channel 21 itself, in addition to the water flow when flowing down the rapid flow channel 35. It flows toward the other end side (downstream side). The drinking water W flowing through the slow flow channel 21 is introduced into the drainage zone 22 through the cutouts 321 on both sides of the drainage zone cover portion 32. The drinking water W introduced into the drainage zone 22 is filtered through the filter 25 and then introduced into the pump chamber 23 through the water passages 16 and 17.

  In this way, while drinking water W circulates in the automatic water dispenser, pets such as dogs and cats appropriately drink water W flowing through the water surface opening portion such as the overflow portion 31, the rapid flow channel 35 or the slow flow channel 21. .

  According to the circulation type automatic water dispenser for pets of the present embodiment configured as described above, since all the drinking water W in the circulation channel flows without any delay, in particular, the overflow portion 31, the rapid flow channel 35 and the slow flow channel 21. Since the drinking water W flows without a stagnation in the water surface opening portion such as the water surface, the stagnation in which the water W stays is not formed, and the garbage such as the pet's body hair, the scum and the dust does not stay. Even if dust is mixed into the water W, the dust is quickly sent to the drainage zone 22 together with the water W and is concealed by the drainage zone cover portion 32. Therefore, garbage does not float on the water surface of the water surface opening portion, and it is possible to reliably prevent a problem that the pet drinks garbage together with the water W, ensuring good aesthetics and being hygienic. Water supply environment can be provided.

  In addition, the drinking water W that has flowed into the drainage zone 22 is introduced into the pump chamber 23 via the water passages 16 and 17 after the mixed dust is removed by the filter 25. Therefore, also in this respect, it is possible to reliably prevent the drinking water W mixed with unnecessary substances such as dust from flowing through the water surface opening portions such as the overflow portion 31, the rapid flow channel 35 and the slow flow channel 21.

  Furthermore, in this embodiment, the front peripheral edge inner wall 121 in the peripheral wall 12 of the water bowl 1, that is, the side wall on the outer side (one side) of the slow flow water channel 21 is formed as an inclined surface that is inclined downward toward the outer side. . For this reason, the drinking water W that has flowed down from the rapid water channel 35 forms a flow of the water W from the inside toward the outside in the slow flow channel 21, and the drinking water W flows a lot along the flow. Accordingly, in the slow flow channel 21, the flow of the drinking water W is faster on the outer side than on the center side (inner side), and dust can be smoothly guided to the outer side. As a result, dust can be efficiently removed from the slow flow water channel 21, and it is possible to more reliably prevent stagnation.

  In the automatic water dispenser of the present embodiment, since the drinking water W is vigorously introduced from the rapid water channel 35 to the slow water channel 21, the drinking water W is appropriately agitated so that dust floats on the water surface. Can be prevented. For this reason, the dust mixed in the water W can be more reliably sent to the drainage zone 22, and the aesthetic appearance and the sanitary environment can be further improved.

  Moreover, in the automatic water feeder of this embodiment, while forming the water flow paths 16 and 17 from the bottom face of the drainage zone 22 to the pump chamber 23, the upstream end opening of the water flow paths 16 and 17, that is, the drainage zone 22 Since the filter 25 is horizontally disposed on the bottom surface, the entire filter can be effectively used as a dust collection region (filtration region), and dust can be collected efficiently. That is, if a water passage hole communicating between the drainage zone 22 and the pump chamber 23 is formed in the partition wall 15 and the like, and a filter is installed in the water passage hole in a vertical arrangement, the water level in the drainage zone 22 decreases. A part of the filter may be disposed on the water surface. In that case, the part on the water surface of the filter does not function as a dust collecting part (filtering part), and the entire filter cannot be used effectively.

  Therefore, in this embodiment, since the filter 25 is installed on the bottom surface of the drainage zone 22, the filter 25 is always disposed below the water surface regardless of the water level in the drainage zone 22. Therefore, even if the water level becomes low, as long as the water W is circulating, the entire filter can function as a dust collecting part (filtering part), and dust can be collected (filtered) efficiently.

  Furthermore, since the filter 25 is installed on the bottom surface of the drainage zone 22, the dust that has settled on the bottom surface can be reliably collected by the filter 25, and the filtration performance can be further improved.

  Furthermore, in this embodiment, since the filter 25 is installed on the bottom surface of the drainage zone 22, a large installation area of the filter 25 can be secured. Therefore, as in the present embodiment, the filter 25 having a size corresponding to almost the entire bottom surface of the drainage zone 22, that is, a large filter 25 having a large filtration area can be employed without difficulty, and the filtration performance is further improved. Can be made.

  Furthermore, in the present embodiment, the recessed portion 16 is formed on the bottom surface of the drainage zone 22, and the filter 25 is fitted into the recessed portion 16, so that the upper surface of the filter 25 matches the bottom surface of the drainage zone 22. Therefore, the filter 25 can be fitted in the drainage zone 22 and can be adapted well, and the aesthetics can be further improved.

  In the present embodiment, since the bottom surface of the pump chamber 23 is set lower than the bottom surface of the slow flow water channel 21, that is, the bottom surface of the water surface opening portion of the water storage chamber 20, the water level in the pump chamber 23 is inadvertently lowered. Can be recognized in advance, and problems such as stoppage of the pumping pump 26 due to water shortage can be effectively prevented. That is, in order to operate the pumping pump 26 reliably, it is necessary to secure a water level in the pump chamber 23 that is equal to or higher than a predetermined water level (minimum water level Lb). This water level is relatively high. For example, some ordinary users have apologized that the pumping pump 26 can be operated without difficulty if a little water W remains even if the water level is lower than the predetermined water level. There are also users who have it.

  Under such a background, if the bottom surface of the pump chamber 23 is set at the same height or higher than the bottom surface of the water storage chamber 20, the water level in the pump chamber 23 is higher than a predetermined water level (minimum water level). Even if it is low, some water W remains in the water storage chamber 20 such as the slow flow channel 21 and the user misidentifies that the amount of water is sufficient. As a result, the timing of replenishing the water W is missed, water shortage occurs, and a problem such as the pumping pump 26 stopping and the circulation of the water W stagnating occurs.

  Therefore, in the present embodiment, since the bottom surface of the pump chamber 23 is set lower than the bottom surface of the slow flow channel 21, the water level in the pump chamber 23 can be sufficiently secured even if the water level of the slow flow channel 21 is low. . In other words, when the water level in the pump chamber 23 is low and water supply is required, since the water W hardly remains in the slow flow channel 21, the user can determine the remaining amount of water W in the slow flow channel 21. If it sees, it can grasp | ascertain easily and correctly whether water supply is required. For this reason, it is possible to reliably prevent a user from overlooking the time of water supply, to reliably supply water W when necessary, and to reliably prevent problems such as a pump stop due to water shortage.

  Furthermore, in this embodiment, since the bottom surface of the pump chamber 23 is set lower than the bottom surface of the drainage zone 22, the potable water W is allowed to flow from the drainage zone 22 through the water passages 16, 17 by the natural flow. It can flow smoothly in.

  In addition, in the said embodiment, although the overflow part 31 in the top funnel 3 is formed in the dish shape (concave spherical shape) recessed downward, it is not restricted to it, In this invention, the overflow part 31 is planar. Alternatively, it may be formed in a mountain shape (convex spherical shape) bulging upward.

  Moreover, in the said embodiment, although the slow flow channel 21 is comprised by the gentle slope which inclines below gradually toward the downstream (other end side) from the upstream (one end side), it is not restricted only to this. In the present invention, the gentle flow channel 21 need not be provided with a gradient. For example, when the slow flow channel 21 is formed almost horizontally (flat) without any gradient from one end side to the other end side, when drinking water W flows from the rapid flow channel 35 to one end side of the slow flow channel 21. The potable water W may flow from one end side to the other end side of the slow flow channel 21 by the momentum (inertial force) of the water W.

  Further, when a gentle slope is formed in the slow flow water channel 21, it is not always necessary to provide a gradient over the entire area of the slow flow water channel 21, and at least a part of the slow flow water channel 21 may be constituted by a gentle slope.

  Moreover, in the said embodiment, in the slow flow water channel 21, it is comprised so that the water W may flow from the left side to the right side, but it cannot be overemphasized in this invention that water flows through the slow flow water channel 21 from the right side to the left side. You may comprise.

 Moreover, in the said embodiment, although the front-periphery edge part of the water bowl 1 is formed in planar view arc shape, in this invention, it is not necessary to form the outer periphery front edge part of water bowl itself in planar view arc shape. Rather, the slow flow channel provided in the water bowl may be formed in an arc shape in plan view. That is, if the slow flow channel is formed in an arc shape in plan view, the outer peripheral shape of the water bowl itself is not particularly limited, for example, a polygon such as a circle, an ellipse, an oval, a triangle, a quadrangle, or a different shape. Etc.

  The automatic circulation water dispenser for pets of the present invention can be used for supplying drinking water for pets such as dogs and cats.
