The companion animal water feeder of the present invention is basically provided with a water temperature control device disposed inside the water tank 10 to receive water to control the temperature of the water accommodated in the water tank 10.

The water whose temperature is adjusted in this way is transferred to the inner assembly 100 by the pump 20 and supplied to the outside.

In this regard, the configuration and operation of a companion animal water supply device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 10.

First, referring to Figures 1 and 3, the circulating structure of the companion animal water supply according to an embodiment of the present invention will be described.

The companion animal water feeder of the present invention includes a water tank (10) in which water is stored, a pump (P) installed in the water tank (10) to feed water stored in the water tank (10), and water discharged from the pump (P). It may include a water supply pipe (L) to be transferred, and a water supply plate (110) overflowing water supplied from the water supply pipe (L).

Between the water tank 10 and the water supply plate 110, a drip tray 120 for receiving water dropped from the water supply plate 110 and discharging it back to the water tank 10 may be disposed.

Specifically, the water dropped from the water supply plate 110 is moved to the drain hole 121 partially formed in the drip tray 120 and then falls into the water tank.

Therefore, the water of the water tank may be circulated while passing through the pump P, the water supply plate 110 and the drip tray 120, and the like.

Additionally, inside the water tank 10, before the water stored in the water tank 10 flows into the pump P, a filtration filter F that filters foreign substances contained in the water may be further installed.

The coupling structure of the water tank 10 and the inner assembly 100 according to an embodiment of the present invention will be further described with reference to FIGS. 1 to 3 again.

 The companion animal water feeder according to an embodiment of the present invention includes a water tank 10 and an inner assembly 100 disposed in the water tank 10 to receive and supply water from the water tank 10.

That is, the companion animal water supply according to an embodiment of the present invention is composed of two parts, a water tank 10 and an inner assembly 100.

The inner assembly 100 may include a water supply pipe (L), a water supply plate 110 and a drip tray 120.

Furthermore, the water supply pipe (L), the water supply plate 110 and the drip tray 120 may be integrally combined to form a single inner assembly 100.

Next, with reference to Figures 3 to 9 will be described in detail the structure and structure of the water temperature control device 40 and the water tank 10 according to an embodiment of the present invention.

First, the water temperature control device 40 will be described first with reference to FIGS. 3, 4, 8, and 9.

Companion animal water supply according to an embodiment of the present invention may include a water temperature control device 40 to realize an optimal water temperature suitable for drinking animals.

For example, when the water temperature sensed by the water temperature sensor TS exceeds the optimal water temperature of the drinking water, the water temperature control device 40 cools the water contained in the water tank 10 to adjust the water temperature suitable for drinking.

The water temperature regulating device 40 includes a thermoelectric element 41 having heat and endothermic functions.

The thermoelectric element 41 can generate and absorb heat by the Peltier effect.

Specifically, the thermoelectric element 41 is a structure in which two different types of metals are joined, and when a direct current is applied, a heating phenomenon may occur in one bonding metal and heat may occur in the other bonding metal.

In addition, if the direction of the applied direct current is reversed, each of the heat generating surface and the heat absorbing surface may be converted into the heat absorbing surface and the heat generating surface.

The companion animal water feeder according to an embodiment of the present invention can control the water temperature of water stored in the water tank 10 through heat absorption or heat generated from the thermoelectric element 41 by including the thermoelectric element 41.

In the embodiment of the present invention, the upper side of the thermoelectric element 41 is assumed to be an endothermic surface, and the lower side is assumed to be a heating surface. However, as described above, the positions of the heat absorbing surface and the heat generating surface are not limited to the above-described substrate, and may be modified by manipulation of a current application direction.

A heat transfer layer 42 may be disposed above the thermoelectric element 41.

The heat transfer layer 42 may transfer the heat of water accommodated in the water tank 10 to the thermoelectric element 41 when the thermoelectric element 41 absorbs heat.

However, the role of the heat transfer layer 42 is not limited to the above description, and conversely, the upper side of the thermoelectric element 41 may transfer heat to water accommodated in the water tank 10 during heat generation.

The heat transfer layer 42 may be formed of a metal material having excellent thermal conductivity, and may include, for example, aluminum (Al) and copper (Cu). The constituent material of the heat transfer layer 42 is not limited to this, and it will be said to include a material that can be easily applied by a person skilled in the art.

The heat transfer layer 42 is plate-shaped, and has a larger area than the thermoelectric element 41, overlapping all of the heat absorbing surfaces of the thermoelectric element 41, thereby effectively absorbing heat from the water contained in the water tank 10 to the heat absorbing surface of the thermoelectric element 41. Can deliver.

 The water temperature control device 40 may radiate heat generated from the thermoelectric element 41 to the outside, including the heat sink 43.

Specifically, the heat sink 43 has a plurality of partition walls 43a forming a gas flow path in at least one direction on one surface, and a thermoelectric element 41 may be disposed on the other surface opposite to the one surface.

That is, the heat transferred from the heat generating surface of the thermoelectric element 41 to the other surface of the heat sink 43 may move to one surface of the heat sink 43 and radiate heat to the outside.

Since a plurality of partition walls 43a are disposed on one surface of the heat sink 43 to form a gas flow path in at least one direction, heat transferred from the other surface can be easily radiated to the outside by a large surface area.

In this specification, the gas flow path in at least one direction is a direction in which air is formed when a plurality of partition walls 43a are arranged in parallel, and a plurality of air movement directions may be formed according to the shape and arrangement structure of the partition walls 43a. have.

8 and 9 again, the water temperature control device 40 according to an embodiment of the present invention is disposed on the edge of the other surface of the heat sink 43, and may further include an annular support 44 having a certain thickness. have.

Since the support 44 surrounds the edge of the other surface of the heat sink 43, the thermoelectric element 41 may be disposed in the inner space surrounded by the support 44 on the other surface of the heat sink 43.

The support 44 can stably support the coupling structure of the heat sink 43, the thermoelectric element 41 and the heat transfer layer 42.

That is, the support 44 can be coupled to the heat transfer element 43 and the heat transfer layer 42 firmly with the thermoelectric element 41 therebetween.

Specifically, at least a portion of the rear surface of the heat transfer layer 42 having a larger area than the thermoelectric element 41 may be coupled to the upper surface of the support 44. The rear surface of the support 44 may be coupled to the top surface of the heat sink 43.

The bonding structure of the heat transfer layer 42, the support 44, and the heat sink 43 can be applied using a known bonding method known in the art.

Further, the thickness of the support 44 is greater than the thickness of the thermoelectric element 41, the thermoelectric element 41 and the heat transfer layer 42 may be spaced apart from each other, the heat transfer between the heat transfer element 41 and the heat transfer layer 42 Paste 45 may be disposed.

Specifically, the heat transfer paste 45 may be disposed between at least one of the heat transfer element 41 and the heat transfer layer 42 and between the heat transfer element 41 and the heat sink 43.

The heat transfer paste 45 is a liquid metal thermal paste that contains a metal material and is disposed between the heat transfer element 41 and the heat transfer layer 42 and between the heat transfer element 41 and the heat sink 43. It can remove the air layer or fill the gap to improve the thermal conductivity.

Therefore, the heat of the water accommodated in the water tank 10 is transferred to the heat absorbing surface of the thermoelectric element 41 through the heat conductive layer 42 and the heat transfer paste 45. On the other hand, heat generated from the thermoelectric element 41 is radiated to the outside through the heat transfer paste 45 and the heat dissipation layer 43.

That is, the water temperature control device 40 according to the embodiment of the present invention does not expose the heating element or the heat absorbing element such as the thermoelectric element 41 to the water contained in the water tank 10 as direct heat transfer.

Instead, the water contained in the water tank 10 is cooled or heated as an indirect heat transfer using the heat conductive layer 42 and the heat transfer paste 45.

The water temperature control device 40 according to the embodiment of the present invention can effectively protect the thermoelectric element 41 from external impact by using an indirect heat transfer method.

 Specifically, by using a heat transfer member such as the heat transfer layer 42 and the heat transfer paste 45, it is possible to minimize the impact transmitted to the heat transfer element 41.

For example, even if an impact is applied to the heat transfer layer 42, since the heat transfer layer 42 is firmly coupled to the support 44, most of the impact applied to the heat transfer layer 42 is applied to the support 44. It is transmitted, and the rest of the impacts are also absorbed by the heat transfer paste 45, which is a liquid phase.

Therefore, it is possible to minimize the impact transmitted to the thermoelectric element (41).

Likewise, even if an impact is applied to the heat sink 43, most of the shock applied to the heat sink 43 is transmitted to the support 44, and the rest of the shock can also be absorbed by the heat transfer paste 45.

In addition, the water temperature control device 40 according to an embodiment of the present invention can prevent an abrupt temperature change of water accommodated in the water tank 10 by using an indirect heat transfer method.

When the heating element or the heat absorbing element is heated or cooled by direct contact with water, a sudden increase or decrease in water temperature may occur, and thus it may be a water temperature not suitable for drinking by a companion animal.

Therefore, the water temperature control device 40 according to an embodiment of the present invention can be controlled to change the water temperature gently by using an indirect heat transfer method using the heat transfer paste 45 and the heat transfer layer 42.

Next, the arrangement structure of the water tank 10 and the water temperature control device 40 will be described in detail.

Specifically, the water tank may include a bottom plate 11 including a first opening 11a and an edge wall 12 surrounding the edge of the bottom plate 11.

At least a portion of the heat transfer layer 42 may be disposed in the first opening 11a.

Specifically, referring to FIGS. 5 and 6, the heat transfer layer 42 is disposed in the first opening 11a of the bottom plate 11 to shield the first opening 11a, and the edge wall 12 is the bottom. While surrounding the edge of the plate 11 can form a receiving space in which water can be accommodated.

Therefore, when water is accommodated in the accommodation space formed by the bottom plate 11 and the border wall 12, the received water comes into contact with the heat transfer layer 42 disposed in the first opening 11a, and the water is transferred to the heat transfer layer ( 42) in the area in contact with the thermoelectric element 41 and water can exchange heat with each other.

Referring to FIG. 7, a blanking plate 13 may be disposed on the bottom plate 11.

The cover plate 13 does not expose the components disposed on the bottom plate 11 to the outside, thereby improving the aesthetic appearance.

Even if the cover plate 13 is disposed on the bottom plate 11, water accommodated in the water tank 10 can freely exchange heat with the heat transfer layer 42.

Specifically, the cover plate 13 is not in close contact with the bottom plate 11, and is disposed on a part of the upper portion protruding upward from the bottom plate 11 to be spaced apart from the bottom plate 11.

Therefore, the water accommodated in the water tank 10 can be freely moved as shown by the arrow to the space between the cover plate 13 and the bottom plate 11 to exchange heat with the heat transfer layer 42.

 Referring to FIG. 7 again, the water tank 10 includes a base plate 14 in the form of a plate, and a base top plate that shields the upper openings of the cylindrical base edge walls 15a and the base edge walls 15a ( It includes a base 16 including a base cover 15, which covers one surface of the base plate 14, including 15b).

In the present specification, the cylindrical shape does not include only geometric shapes such as cylindrical and horn-shaped, but includes a structure in which the cross section in the horizontal direction has a closed loop shape.

The base 16 may include a base plate 14 and a base cover 15 covering one surface of the base plate 14 to form a space inside the base.

Other parts may be accommodated and disposed in the space inside the base.

The base 16 is disposed on the bottom surface of the bottom plate 11 to be firmly coupled to the bottom plate 11 and the edge wall 12.

The water temperature control device 40 in which the heat transfer layer 42 is disposed in the first opening 11a may be disposed over the bottom plate 11 and the base 16.

Specifically, the base top plate 15b includes a second opening 15c, and a water temperature adjusting device may be disposed over the first opening 11a and the second opening 15c.

Therefore, the water temperature control device 40 is disposed in the interior space of the base 16 formed by the base plate 14 and the base cover 15 over the second opening 15c.

Next, with reference to FIGS. 8 to 10, the heat dissipation configuration and structure of the water temperature control device according to an embodiment of the present invention will be described.

As described above, the water temperature control device 40 according to an embodiment of the present invention generates heat and heat at the same time, and it is necessary to smoothly dissipate heat generated from the thermoelectric element 41 to realize a desired level of heat absorption.

The water temperature control device according to an embodiment of the present invention may further include a heat dissipation fan 50 to perform smooth heat dissipation.

Specifically, the heat dissipation fan 50 is disposed on one side of the heat dissipation plate 43, and in particular, may be disposed on one side of the heat dissipation plate 43 corresponding to the gas flow path in one direction formed by the partition wall 43a.

The air flow formed by the heat dissipation fan 50 passes through the partition wall 43a and receives heat transferred to the partition wall 43a to radiate heat to the outside of the companion animal water supply.

The heat dissipation fan 50 is disposed on one side of the heat dissipation plate 43 corresponding to the one-way gas flow path, thereby effectively performing heat dissipation.

Since the heat dissipation fan 50 according to the embodiment of the present invention is disposed on one side of the heat dissipation plate 43 corresponding to the one-way gas flow path of the heat dissipation plate 43, airflow generated from the heat dissipation fan 50 is a partition wall 43a The airflow direction does not change within.

Therefore, the air that has received heat from the partition wall 43a does not escape to the outside, and prevents the phenomenon of being trapped inside the partition wall 43a, thereby effectively dissipating heat.

In addition, the heat dissipation fan 50 includes a fan fan 52 and a fan housing 52 housing the blower fan 51, and the fan housing 52 may include a discharge port 53 facing the one direction. have.

The discharge port 53 of the heat dissipation fan 50 may be spaced apart from the heat sink 43 by a predetermined distance, and the area of the discharge port 53 may be smaller than the area of the one side of the heat sink 43.

By controlling the area of the discharge port 53 of the heat dissipation fan 50 to be relatively small, the airflow supplied from the heat dissipation fan 50 can have high directionality.

In addition, by discharging the discharge port 53 from one side of the heat dissipation fan 43, and controlling the area of the one side relatively large, the airflow supplied from the discharge port 53 is diffused to diffuse one side of the heat sink 43 Can be sprayed evenly.

The base plate includes an intake port 14a and an exhaust port 14b formed by a plurality of through holes.

The airflow generated by the heat dissipation fan 50 may be supplied with air by the intake port 14a and discharged to the outside by the exhaust port 14b.

Specifically, the intake 14a is arranged to correspond to the heat dissipation fan 50 from the bottom of the heat dissipation fan 50, and the exhaust port 14b is of a heat sink 43 opposite to the one side on which the heat dissipation fan 50 is disposed. It is disposed in the heat dissipation plate 14 portion corresponding to the other side.

It is natural that there is a through hole for receiving air from the inlet 14a on the lower side of the fan housing 52.

Therefore, the gas introduced into the base 16 through the intake port 14a moves to the heat sink 43 by the heat sink fan 50, and the gas that receives heat from the heat sink 43 is passed through the exhaust port 14b. It is released to the outside.

In particular, the inclination of the through hole formed in the exhaust port 14b may be about 20 degrees to 60 degrees based on the heat sink side.

More specifically, the inclination of the through hole may be about 45 degrees.

In this specification, the inclination of the through hole means an angle between the center of the lower opening of the through hole and the center of the upper opening forming the base plate 14.

By forming the inclination of the through hole formed in the exhaust hole 14b at about 45 degrees from the side of the heat sink adjacent to the through hole, air flow through the heat sink 43 can be easily passed through the through hole of the exhaust hole 14b and discharged to the outside.

However, the inclination of the through hole may be formed not only in the exhaust port 14b, but also in the intake port 14a.

The companion animal water feeder according to an embodiment of the present invention is disposed in the inlet 14a and the outlet 14b on the base plate 14 so that it is not apparent to the user's eyes in appearance, which is advantageous in appearance.

In addition, it is possible to prevent the companion animal from blocking or damaging the intake port 14a or the exhaust port 14b by stimulating the companion animal because it is not exposed to the companion animal's eyes.

The air sucked in and exhausted through the intake 14a and the exhaust 14b is a gas, and in order to effectively dissipate heat, the air flow must have high directionality. However, it is difficult to derive an airflow having excellent directivity with the gas itself.

Therefore, the companion animal water supply according to the embodiment of the present invention may include a structure capable of blocking air leaking into the base 16 and guiding air sucked and exhausted in order to realize high airflow directionality.

 Specifically, it may include a heat sink receiving portion 60 that accommodates the heat radiation fan 50 and has both sides corresponding to the one direction open.

The heat sink accommodating part 60 includes a pair of accommodating part side walls 61 and a pair of accommodating part bottom plates 62 that shield the bottoms of the pair of accommodating part side walls 61, and a gas flow path formed in the heat sink 43 The side surface corresponding to one direction of the opening may accommodate the heat sink 43.

The heat sink accommodating part 61 covers the bottom and side surfaces of the heat sink 43 to prevent the air flowing into the heat sink 43 from flowing out.

In addition, an intake guide wall 70 connecting the edge of the discharge port 53 and the edge of the opening surface of the heat sink receiving portion 60 adjacent to the discharge port 53 may be included.

The air diffused when spraying from the discharge port (53) to the heat sink (43) is guided to the intake guide wall (70) to prevent air from leaking to the outside.

Additionally, an exhaust guide wall 80 surrounding the exhaust port 14b and connecting an edge of the opening surface of the heat sink receiving portion 60 adjacent to the exhaust port 14b may be further included.

The exhaust guide wall 80 is connected to the heat sink accommodating portion 60 and surrounds the exhaust port 14b to guide the air passing through the heat sink 43 to be discharged to the exhaust port 14b without leaking to the outside.

Referring to FIGS. 8 and 9 again, the upper surfaces of the heat sink receiving portion 60, the intake guide wall 70, and the exhaust guide wall 80 may be opened, but they may all be covered by the base top plate 15b. have.

That is, the portion except the intake port 14a and the exhaust port 14b is formed by the base top plate 15b, the heat sink accommodating portion 60, the intake guide wall 70, and the exhaust guide wall 80 to form a closed gas flow path pipe. can do.

As described above, the gas flow path pipe formed as described above does not leak air to the outside of the gas flow path pipe, and discharges air to the outside to effectively radiate heat.

In addition, repair and maintenance can be facilitated by covering the upper opening surfaces of the heat sink receiving portion 60, the intake guide wall 70, and the exhaust guide wall 80 together by the base top plate 15b.

Specifically, when only the base top plate 15b is removed, the water temperature control device 40 is exposed, so that the configuration of the water temperature control device can be easily managed and repaired compared to the case where the housing is independently housed.

However, the upper opening surfaces of the heat sink receiving portion 60, the intake guide wall 70 and the exhaust guide wall 80 are not covered only by the base top plate 15b, and the heat sink receiving portion 60, the intake guide wall ( 70) and each of the exhaust guide walls 80 may extend from the upper side to individually cover the upper opening surface.

Above, although the embodiments of the present invention have been illustrated and described, the present invention is not limited to the specific embodiments described above, and is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made by a person skilled in the art, and these modifications should not be individually understood from the technical idea or prospect of the present invention.
