Description

  The present invention relates to a circulating automatic water dispenser for pets used when supplying drinking water for pets such as dogs and cats.

  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 water dispenser for pets is provided with a water bowl for storing water, an overflow portion provided above the water bowl, and an inclined water channel arranged from the overflow portion to the water bowl. The potable water is circulated by pumping it up by a circulation pump and flowing it out of the overflow 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 circulation type automatic water dispenser, if the flow rate of drinking water flowing out from the overflow portion is small, the appearance is poor and aesthetically undesirable. Furthermore, the circulation amount of water is reduced, which is not preferable for hygiene purposes.

  Therefore, if a large circulation pump with a high head is used to ensure a sufficient flow rate of water, the flow rate can be secured, but the momentum of the water blown from the discharge port of the circulation pump becomes too strong, and the overflow section The water that flows out of the water will be blown up like a fountain. If it does so, the subject that water will scatter and the water supply area will be contaminated with water will generate | occur | produce.

  The present invention has been made in view of the above-mentioned problems, and while ensuring a sufficient flow rate of water flowing out from the overflow portion, it is possible to moderately suppress the water flow and prevent water from spattering and scattering. An object of the present invention is to provide a circulating automatic water dispenser for pets.

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

[1] A pumping pump installed in a water bowl, a flooding unit provided above the pumping pump, a water supply pipe connecting a discharge port of the pumping pump to an outlet of the overflowing unit, and the overflowing unit The water in the water bowl pumped up by the pump is discharged to the overflow portion through the water supply pipe and the outlet, and A circulating automatic water dispenser for pets in which water flows down the inclined water channel and returns into the water bowl,

  According to the circulation type automatic water dispenser for pets of the invention [1], the baffle plate is disposed in the water supply pipe that connects the discharge port of the pump and the outlet of the overflow portion. The discharged water is reduced in momentum by the baffle plate, and gradually flows through the water supply pipe. For this reason, it is possible to reliably prevent a problem that the water spouts and scatters while allowing the water to flow out from the outlet of the overflow portion with a sufficient amount of water.

  According to the circulation type automatic water dispenser for pets of the invention [2], since the baffle plate is supported by the discharge port of the pump, the relative position of the baffle plate with respect to the discharge port can be fixed to prevent displacement. it can. For this reason, the water discharged from a discharge outlet can be made to contact | abut to a baffle plate reliably, and a water flow can be reduced reliably.

  According to the circulation type automatic water dispenser for pets of the invention [3], since the sealing member is attached to the lower end of the water supply pipe to achieve water tightness, the water pumped into the water supply pipe leaks from the lower end of the water supply pipe. Backflow can be prevented.

In the water bowl 1, the pump chamber 23 and the drainage zone 22 communicate with each other through the recessed portion 16 and the water passages 17, 17 so that the drinking water W in the drainage zone 22 passes through the recessed portion 16 and the drainage zone 22. It flows into the pump chamber 23 through the water flow ports 17, 17.

  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, 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 on the front half of the inner wall of the peripheral wall 12 is disposed so as to be inclined inward. 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 an outlet 37. Further, the lower end of the water supply pipe 37 is arranged corresponding to the pump chamber 23.

  As shown in FIGS. 4 and 8, a pumping pump (circulation pump) 4 is installed in the vicinity of the partition wall 15 at an intermediate position in the left-right direction inside the pump chamber 23. A pipe-like discharge part 41 is provided on the upper wall of the pump 4 so as to protrude upward. Further, a number of slit-like notches are formed in the lower part of one side wall of the pump 4, and each notch is configured as a suction port 42. In the pump 4, the drinking water W near the bottom is sucked from the suction port 42 and discharged upward from the upper end of the discharge part 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 pumping pump 4 is installed.

  As shown in FIGS. 7 to 9, the discharge port member 5 is attached to the discharge portion 41 of the pumping pump 4. The discharge port member 5 is constituted by a hard synthetic resin molded product integrally provided with an attachment portion 50, an extension portion 51, a column portion 52, and a baffle plate 53.

  The mounting portion 50 has a pipe shape whose outer diameter is slightly larger than the discharge portion 41 of the pumping pump 4, and can be fitted and fixed to the discharge portion 41 of the pumping pump 4.

  The extension portion 51 has a pipe-like shape in which the base end (lower end) is integrally formed with the tip end (upper end) of the attachment portion 50. The extension 51 has an outer diameter dimension that is substantially the same as that of the discharge part 41 of the pump 4. In other words, the extension portion 51 has a slightly smaller outer diameter than the attachment portion 50, and an outer peripheral step portion 55 is formed between the outer peripheral surface of the extension portion 51 and the outer peripheral surface of the attachment portion 50.

  The struts 52 have a base end (lower end) formed integrally with a tip end (upper end) of the extension portion 51, and three support columns 52 are formed at equal intervals in the circumferential direction. Needless to say, in the present invention, the number of support portions 52 is not limited, and may be two or less or three or more. Further, the shape of the support portion 52 is not particularly limited.

  The baffle plate 53 has a disk-like shape that is fixed to the tip of the column portion 52 and has an outer diameter dimension that is substantially the same as that of the extension portion 51.

    The attachment portion 50, the extension portion 51, and the baffle plate 53 are arranged so that their axial centers coincide with each other, and the baffle plate 53 is arranged to face the upper end opening of the extension portion 51.

  The discharge port member 5 is attached to the pumping pump 4 by externally fitting the mounting portion 50 of the discharge port member 5 to the discharge unit 41 of the pumping pump 4. In this attached state, the extension 51 of the discharge port member 5 is arranged so that the axis coincides with the discharge 41 of the pumping pump 4 and the extension 51 extends upward with respect to the discharge 41. Yes.

  Here, in the present embodiment, the discharge portion 41 and the extension portion 51 constitute a discharge pipe, and the upper end (tip) opening portion of the discharge pipes 41 and 51, that is, the upper end opening portion (tip opening) of the extension portion 51. Part) is configured as the discharge port 45 of the pumping pump 4. Therefore, in the present embodiment, the baffle plate 53 is disposed so as to face the discharge port 45 of the pumping pump 4. Further, the baffle plate 53 is supported by the discharge port 45 of the pumping pump 4 through a support column 52 as a support.

  In this configuration, the water W discharged from the discharge part 41 of the pump 4 is diffused in the outer diameter direction by passing through the extension part 51 of the discharge port member 5 and colliding with the baffle plate 53, and diffused. The water W flows between the support columns 52 and flows out of the discharge port member 5.

  In addition, in this embodiment, although the discharge port member 5 is comprised separately from the discharge part 41 of the pumping pump 4, it is not restricted only to it, In this invention, the discharge port member 5 is made into the discharge part of the pumping pump 4. 41 may be integrally formed.

  As shown in FIGS. 7 and 10, a sealing cap 6 is attached to the lower end of the water supply pipe 36 of the top funnel 3.

  The sealing cap 6 is made of a material having elasticity, and a ring-shaped sealing portion 61 and a peripheral wall portion 62 formed so as to rise upward from the outer peripheral edge of the sealing portion 61 are integrated. I have. The central hole (ring hole) of the seal portion 61 is formed so that its inner diameter is smaller than the outer diameter of the extension portion 51 of the discharge port member 5. In the present embodiment, a seal member is constituted by the seal portion 61 of the seal cap 6.

  The peripheral wall portion 62 of the sealing cap 6 is externally fitted to the lower end portion of the water supply pipe 36 in the top funnel 3 in an elastic contact state, so that the sealing cap 6 is detachably attached to the lower end portion of the water supply pipe 36. ing.

  Further, the baffle plate 53 and the support column 52 of the discharge port member 5 are inserted into the center hole of the seal portion 61 in the seal cap 6 from below, and the extension portion 51 is inserted into the center hole of the seal member 61. . Further, when the seal portion 61 is pressed against the lower end surface of the water supply pipe 36 by the outer peripheral step portion 55 of the discharge port member 5, the seal portion 61 is sandwiched and fixed by the water supply pipe 36 and the discharge port member 5.

  Here, since the inner diameter of the central hole of the seal portion 61 is formed smaller than the outer diameter of the extension portion 51, the inner peripheral edge of the seal portion 61 is bent upward and the central hole is expanded in diameter. The extension portion 51 is inserted and disposed in the central hole of the seal member 61. As described above, the seal member 61 is elastically adhered to the outer peripheral surface of the extension portion 51 in a watertight state, so that the gap between the inner peripheral surface of the water supply pipe 36 and the outer peripheral surface of the extension portion 51 is reduced at the lower end opening of the water supply pipe 36. The watertightness is achieved by the seal portion 61.

  Thus, the discharge part 41 of the pumping pump 4 is connected to the water supply pipe 36 of the top funnel 3 via the discharge port member 5 and the sealing cap 6. Thereby, the drinking water W in the pump chamber 23 sucked up by the pumping pump 4 is supplied to the overflow portion 31 from the outlet 37 at the upper end through the water supply pipe 36, overflows from the overflow portion 31 and flows into the rapid flow channel. 35 is discharged. As already described, since the seal portion 61 provides watertightness between the inner peripheral surface of the water supply pipe 36 and the outer peripheral surface of the extension 51 at the lower end opening of the water supply pipe 36, The internal water can be prevented from leaking from the lower end opening of the water supply pipe 36.

  As shown in FIGS. 1-4, in this embodiment, the rapid water channel 35 in the top funnel 3 comprises the 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 with the drinking water W injected into the water bowl 1 in this manner, the drinking water W in the pump chamber 23 is pumped up by the pumping pump 4 and discharged from the discharge port 45 of the discharge port member 5. The The discharged drinking water W collides with the baffle plate 53 to reduce the momentum, gently rises in the water supply pipe 36, flows out from the outlet 37, and is introduced into the overflow portion 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 circulating automatic water dispenser for pets of the present embodiment configured as described above, the baffle plate 53 is provided in the water supply pipe 36 that connects the discharge port 45 of the pumping pump 4 and the outlet 37 of the overflow portion 31. Due to the arrangement, the potable water W discharged from the discharge port 45 is reduced in vigor by the baffle plate 53 and circulates in the water supply pipe 36 at a low speed. Therefore, since the drinking water W gently flows out from the outlet 37 of the overflow portion 31, it is possible to reliably prevent a problem that the drinking water W is ejected from the outlet 37 and scattered.

  Furthermore, in the present embodiment, although the potable water W discharged from the discharge port 45 of the pumping pump 4 is reduced in momentum, a sufficient flow rate can be secured, so that sufficient potable water is discharged from the outlet 37 of the overflow portion 31. W overflows. For this reason, the amount of water is abundant and good aesthetics can be ensured, and the circulation amount of the quoted water W can be ensured, which is preferable from a hygienic viewpoint.

  Furthermore, in this embodiment, since the baffle plate 53 is supported by the discharge port 45 of the pumping pump 4 via the support | pillar part 52, a water force can be reduced much more reliably so that it may demonstrate below.

  That is, the top funnel 3 having the water pump 36 is separate from the pumping pump 4 and is assembled, so that the top funnel 3 may be displaced with respect to the pumping pump 4. For this reason, if the baffle plate 53 is supported and fixed to the water supply pipe 36 of the top funnel 3, the baffle plate 53 is displaced with respect to the discharge port 45 of the pump 4 due to the displacement of the top funnel 3 with respect to the pump 4. There are things to do. Then, the water W discharged from the discharge port 45 does not reliably hit the baffle plate 53, and the momentum of a part of the water W is not reduced, and the part of the water W passes through the water supply pipe 36 while maintaining the force. To do. As a result, there is a possibility that the water W will be sprayed like a fountain from the outlet 37 of the overflow portion 31 and scattered.

  Therefore, in this embodiment, since the baffle plate 53 is supported by the discharge port 45 of the pumping pump 4, the relative position of the baffle plate 53 with respect to the discharge port 45 can be fixed, and displacement can be prevented. For this reason, since the water W discharged from the discharge port 45 reliably contacts the baffle plate 53, the water force can be reliably reduced in the water supply pipe 36, and the water W is sprayed from the outlet 37 of the overflow portion 31 and is scattered. Such a problem can be reliably prevented.

  Furthermore, in the present embodiment, the baffle plate 53 is supported on the pumping pump 4 side, and the relative position of the baffle plate 53 with respect to the discharge port 45 is fixed, so the baffle plate 53 is attached (with the discharge port member 5). Even if the water pump 4 is used in other water supply devices of different types and sizes, the water flow reducing effect by the baffle plate 53 can be obtained with certainty. That is, the pumping pump 4 with the baffle plate 53 according to the present embodiment can be adopted for other water supply devices without any problems, so that versatility can be improved.

  Moreover, in the present embodiment, since the baffle plate 53 is fixed to the pumping pump 4 side, the baffle plate 53 can be reliably arranged regardless of the material and shape of the top funnel 3. That is, when the top funnel 3 is made of, for example, ceramic that is difficult to be finely processed, it is difficult to assemble the baffle plate 53 to the top funnel 3, but in this embodiment, the baffle plate is disposed on the pumping pump 4 side. Since 53 is fixed, the baffle plate 53 can be reliably attached regardless of the material and shape of the top funnel 3. Thus, regardless of the material of the top funnel 3, the baffle plate 53 can be securely attached, and versatility can be further improved.

  In this embodiment, since the sealing cap 6 is fitted to the lower end of the water supply pipe 36 to achieve water tightness at the lower end of the water supply pipe 36, the water W in the water supply pipe 36 leaks from the lower end and enters the pump chamber 23. Therefore, it is possible to reliably prevent problems such as reverse flow.

  Furthermore, since leakage of the water W from the lower end of the water supply pipe 36 can be prevented, the water W can be reliably circulated even if the water level in the water bowl 1 is low.

  In other words, if the water tightness at the lower end of the water supply pipe 36 is insufficient, the lower end of the water supply pipe 36 is water W when the water level in the water bowl 1 is low and the water surface does not reach the lower end position of the water supply pipe 36. Will not be sealed. Then, the water W sent into the water supply pipe 36 from the pumping pump 4 leaks in a large amount from the lower end of the water supply pipe 36 and flows backward, and the water W cannot be sufficiently supplied to the overflow portion 31, It becomes difficult to circulate the water W sufficiently.

  On the other hand, in this embodiment, since sufficient water tightness can be secured at the lower end of the water supply pipe 36, even if the water level of the water bowl 1 is low and the water surface does not reach the lower end position of the water supply pipe 36, The water W fed into the water supply pipe 36 from the pumping pump 4 does not leak from the lower end of the water supply pipe 36, can be reliably supplied to the overflow portion 31, and the water W can be circulated with a sufficient amount of water. .

  Moreover, in this embodiment, since all the drinking water W of a circulation flow path flows without stagnation, especially in the water surface open | release parts, such as the overflow part 31, the rapid flow channel 35, and the slow flow channel 21, the drinking water W flows without stagnation. Therefore, the stagnation in which the water W stays is not formed, and the garbage such as the pet's body hair, food residue, 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 26 due to water shortage can be effectively prevented. That is, in order to operate the pumping pump 26 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 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.

  In the above embodiment, the case where the baffle plate 53 is supported and fixed to the discharge port 45 of the pumping pump 4 has been described as an example. However, the present invention is not limited thereto, and in the present invention, the baffle plate is a water supply pipe such as a top funnel. You may make it form in the side.

  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.
