The opening 19 communicates between the upper surface side (front surface side) and the lower surface side (back surface side) of the water bowl 1, and the electric cord 45 is connected to the surface side of the water bowl 1 through the opening 19 ( It can be led from the upper surface side to the back surface side (lower surface side).

  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, and 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 inner side of the water bowl 1. The peripheral wall 12 is disposed at a predetermined interval from the inner periphery of the front half.

  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 inner peripheral wall 12 is configured as a slow flow 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, in the pump chamber 23, an electric pump pump 4 constituting an electric device is installed in the vicinity of the partition wall 15 at an intermediate position in the left-right direction. The pump 4 is supported on the bottom surface of the pump chamber 23 with the discharge port 41 arranged upward. Further, the suction port (not shown) of the pumping pump 23 is opened near the bottom surface of the pump chamber 23. Thus, the pump 4 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 41. 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 4 is installed.

  4-7, in this embodiment, in the bottom wall 11 of the water bowl 1, the part corresponding to the drainage zone 22 (the part where the filter 25 is installed) and the pump chamber 23 are provided. Corresponding portions are recessed downward. In other words, in the water reservoir 10 on the back side of the water bowl 1, a portion corresponding to the drainage zone 22 and a portion corresponding to the pump chamber 23 are formed so as to protrude downward. In the present embodiment, the downward projecting portion has a drum shape (cylindrical shape), and is configured as an electric wire winding portion 5 around which the electric cord 45 can be wound along the outer peripheral side surface.

  A plurality of wire holders 50 are provided on the outer periphery of the wire winding part 5 with appropriate intervals in the circumferential direction (winding direction). As shown in FIG. 8, each electric wire holder 50 includes two support claws (a pair of support claws) 51 and 51, and a pushing claw 52. The two support claws 51, 51 are integrally formed so as to protrude outward on the outer peripheral surface of the wire winding portion 5 with a gap in the circumferential direction therebetween. The pushing claws 52 are integrally formed so as to protrude downward on the bottom wall bottom surface of the water reservoir 10 in a state where the pushing claws 52 are arranged correspondingly between the pair of support claws 51, 51.

  On the other hand, one end of an electric cord 45 for supplying power is connected to the pump 4 installed in the pump chamber 23 of the water bowl 1. The electric cord 45 is inserted into the wire insertion opening 19 (see FIGS. 5 and 6) provided at one end of the partition wall 14 in the water bowl 1, so that the back surface side (lower surface side) of the water bowl 1. ).

  Then, as shown in FIG. 7, the electric cord 45 is wound around the outer peripheral surface of the wire winding part 5 in an appropriate amount along the circumferential direction as necessary, and as shown in FIG. The other end is inserted through the notch 14 of the outer peripheral wall 13 of the water bowl 1 and drawn out of the water bowl 1. An AC adapter 46 with a plug is provided at the other end of the electrical cord 45 drawn to the outside (see FIG. 7), and the plug of the AC adapter 46 is connected to a household outlet (not shown).

  Thus, in this embodiment, since the electric cord 45 is wound around the electric wire winding part 5 as needed, the electric cord 45 is pulled out to the outside of the water bowl 1 depending on the winding length (winding amount). The length (withdrawal amount) can be adjusted freely.

  Further, as shown in FIG. 8, in the present embodiment, the electric cord 45 wound around the electric wire winding part 5 can be held by the electric wire holder 50. That is, the portion of the wound electric cord 45 corresponding to the electric wire holder 50 is fitted so as to meander between the pair of support claws 51 and the pushing claws 52 of the electric wire holder 50. As a result, the electric cord 45 is compressed and deformed into a state where the electric cord 45 is pushed between the pair of support claws 51, 51 by the pushing claw 52, and the electric cord 45 is held in this state. In this way, the electric cord 45 is held by the electric wire holder 50 at the required portion, so that the electric cord 45 is reliably held in a state of being wound around the electric wire winding portion 5. Therefore, it is possible to prevent the electric cord 45 from being carelessly loosened and detached from the wire winding part 5, and to prevent the electric cord 45 from being scattered and arranged in a messy state.

  When the wound electric cord 45 is unwound, the electric cord 45 may be pulled downward from between the pair of support claws 51 and the push claws 42 of the electric wire holder 50. Thereby, since the holding | maintenance by the electric wire holder 50 of the electric cord 45 is cancelled | released, the electric cord 45 can be easily unwound from the electric wire winding part 5. FIG.

  As shown in FIG. 4, the lower part of the inner peripheral wall 12 in the front half of the water bowl 1 is disposed so as to be inclined outward. Further, the corner portion between the inner peripheral wall 12 and the bottom wall 11 in the front half circumference has an arc-shaped cross-sectional shape having a radius of curvature.

  In addition, the inner peripheral wall 12 of the front half circumference constitutes an outer side (one side) side wall of the slow flow water channel 21 described in detail later.

  As shown in FIGS. 1 to 4 and 9, the top funnel 3 disposed in the water bowl 1 is formed of, for example, a molded product of a 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 constituted by at least one of the drainage zone cover portion 32 and 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 portion 33 is disposed corresponding to the rear edge of the inner 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 of the inner peripheral wall 12 and the lower end of the drainage zone cover 32 in the water bowl 1. In other words, the slow flow water channel 21 is formed with the front half of the inner peripheral wall 12 as one side (outside) side wall and the lower end of the drainage zone cover portion 32 as 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 41 of the pumping pump 4. Thereby, the drinking water W in the pump chamber 23 sucked up by the pump 4 is supplied from the outlet 37 to the overflow portion 31 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, and in the present invention, at least a part of the rapid water channel 35 is formed with a steep slope. 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 automatic water dispenser for pets of this embodiment, the drinking water W is circulated 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 flow path 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 automatic water dispenser for pets of the present embodiment configured as described above, the drinking water W has a water level slightly lower than the maximum water level (maximum water level) indicated by the virtual line La as shown in FIG. Until it is stored in the water bowl 1. For reference, in the water dispenser of the present embodiment, when the drinking water W is poured into the water bowl 1 up to the maximum water level La, the amount of water is about 950 ml.

  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 4 is driven in the state where the drinking water W is 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 4 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 to one end side (upstream side) of the slow 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. 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, the wire winding part 5 is formed on the back side of the water bowl 1, and the electric cord 45 is surplus in the winding part 5. By winding the portion, the drawing amount (drawing length) of the electric cord 45 drawn to the outside of the water bowl 1 can be freely adjusted. For this reason, the length (drawing part) of the electric cord 45 arranged from the water bowl 1 to the household outlet can be adjusted to the minimum necessary, and there is a surplus part in the drawing part of the electric cord 45 Without being randomly arranged. Therefore, in the present embodiment, the drawn portion of the electric cord 45 can be arranged neatly and well arranged, and a good aesthetic appearance can be secured, and pets such as dogs and cats can bite or play with the drawn portion of the electric cord 45. It can be effectively prevented, and the electric cord 45 can be prevented from being broken or damaged, thereby improving the durability.

  Furthermore, according to the water supply device of the present embodiment, the electric wire winding part 5 is formed in a drum shape projecting downward from the bottom wall 11 of the water reservoir 10, and therefore, along the outer peripheral side surface of the electric wire winding part 5. The operation of winding or unwinding the electric cord 45 can be performed easily and smoothly.

  Furthermore, in the present embodiment, the drainage zone 22 formed by forming the recess 11 in the bottom wall 11 of the water reservoir 10 and the outer peripheral surface of the pump chamber 23 are used as the wire winding part 5. Effective use of the site can be achieved. That is, in this embodiment, it is not necessary to newly form the electric wire winding part 5 separately, and the electric wire winding part 5 can be easily produced correspondingly.

  Further, according to the water supply device of the present embodiment, the electric cord 45 can be held in a state of being wound around the electric wire winding part 5 by the electric wire holder 50, so that the wound electric cord 45 is loosened and detached. It is possible to reliably prevent problems such as being lost.

  In addition, according to the circulation type automatic water dispenser for pets of this embodiment, since all the drinking water W in the circulation flow channel flows without stagnation, the water surface opening portions such as the overflow portion 31, the rapid flow passage 35, and the slow flow passage 21 are provided. Since the drinking water W flows without any stagnation, the stagnation of the water W is not formed, and the garbage of the pet's body hair, food, and 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 4 due to water shortage can be effectively prevented. That is, in order to operate the pumping pump 4 with certainty, it is necessary to secure a water level above a predetermined water level in the pump chamber 23. This water level is relatively high. For example, some ordinary users have apologized that the pumping pump 4 can be operated without any problem if the water W remains a little 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 to the same height or higher than the bottom surface of the water storage chamber 20, the water level in the pump chamber 23 may be lower than a predetermined water level. However, since the water W remains somewhat in the water storage chamber 20 such as the slow flow channel 21, the user mistakenly thinks that the amount of water is sufficient. As a result, the timing of replenishing the water W is missed, water shortage occurs, and the pumping pump 4 is stopped and the water W circulation is delayed.

  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.

  Moreover, in the said embodiment, although the electric wire winding part 5 is formed in the drum shape (cylindrical shape), it is not restricted only to it, In this invention, the shape of an electric wire winding part is not specifically limited. For example, the electric wire winding portion may be configured by a plurality of pin members protruding downward in the water bowl, and configured to be able to wind an electric cord so as to surround the plurality of pin members. In short, as long as the electric cord can be wound, the wire winding part may be formed in any shape.

  Furthermore, in the said embodiment, although the electric wire holder 50 is comprised by a pair of support nail | claw 51 and the pushing nail | claw 52, it is not restricted only to it, In this invention, if it is the structure which can hold | maintain an electric cord so that attachment or detachment is possible. Any configuration may be adopted as the electric wire holder.

  Moreover, in the said embodiment, although the electrical cord is used as an electric wire, other electric wires, for example, an electric cable, an insulated wire, etc., can also be used.

  The pet water supply apparatus of the present invention can be used for supplying drinking water for pets such as dogs and cats.
