First, referring to Figures 2 to 4, the configuration and structure of the water tank will be described.

The water tank 10 may include a bottom plate 11 and an edge wall 12 surrounding the edges of the bottom plate 11.

The space formed by the bottom plate 11 and the rim wall 12 is a receiving space of the water tank 10, and water can be accommodated.

It may include a base cover 15 to cover one surface of the base plate 14, including a base top plate (15b) to cover.

The base plate 14 may be connected to the bottom plate 11 by a base cover 15.

Specifically, the upper surface of the base top plate 15b is coupled to the bottom surface of the bottom plate 11 so that the base 16 and the bottom plate 11 and the edge wall 12 can be firmly connected.

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.

The base plate 14 and the base inner space formed by the base cover 15 may be arranged to accommodate at least a portion of the water temperature control device 40 to be described later.

Next, the water temperature control device 40 will be described with reference to FIGS. 2 and 5 to 7.

Companion animal water supply according to an embodiment of the present invention can implement an optimal water temperature suitable for drinking by a companion animal including a water temperature control device 40.

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, when a current is applied to the thermoelectric element 41, heat absorption occurs on one surface of the thermoelectric element 41 and heat dissipation occurs on the other surface opposite to the one surface. 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.

In the embodiment of the present invention, the thermoelectric element 41 generates heat absorption on the upper side, so that the water accommodated in the water tank 10 can be cooled to control the water temperature.

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.

Specifically, the heat transfer layer 42 is disposed in the hollow portion formed in the bottom plate 11 to directly cool the water contained in the water tank 10.

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 the 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 water temperature control device 40 according to the embodiment of the present invention may radiate heat generated from the thermoelectric element 41 to the outside, including the heat sink 43.

In the thermoelectric element 41, heat absorption and heat generation occur simultaneously, and heat must be smoothly generated on the heating surface, so that heat absorption on the heat absorption surface is smooth.

Therefore, the water temperature control device 40 smoothly discharges heat generated from the thermoelectric element 41 including the heat sink 43. The heat transferred from the heat generating surface of the thermoelectric element 41 to the heat sink 43 may move to one surface of the heat sink 43 to be radiated to the outside.

Specifically, the heat sink 43 is disposed under the thermoelectric element 41, and a plurality of partition walls 43a forming a gas flow path in at least one direction is formed on a lower side opposite to the thermoelectric element 41.

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 disposed, and a plurality of air movement directions may be formed according to the shape and arrangement structure of the partition walls 43a.

Water temperature control device 40 according to an embodiment of the present invention is a heat transfer paste (45, not shown) 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 ) May be further included.

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.

Furthermore, a portion of the shock transmitted from the heat transfer layer 42 or the heat sink 43 to the thermoelectric element 41 may be absorbed to protect the thermoelectric element 41.

Water temperature control device 40 according to an embodiment of the present invention can quickly heat the heat of the thermoelectric element 41, including a heat radiating fan (47).

Specifically, the heat dissipation fan 47 is disposed on the lower surface of the heat sink 43 on which the plurality of partition walls 43a are formed, and may be positioned to allow air to be transmitted to the plurality of partition walls 43a.

Since the heat dissipation fan 47 is disposed under the heat dissipation plate 43 on which the plurality of partition walls 43a are formed, heat generated in the thermoelectric element 41 can be rapidly generated.

That is, since the air delivered from the heat dissipation fan 47 to the heating plate 43 is directly injected onto the surfaces of the plurality of partition walls 43a, the heat dissipation plate 43 can be effectively dissipated.

The air injected from the heat dissipation fan 47 to the surface of the heat sink 43 on which the plurality of partition walls 43a are formed may form vortices or the like in the space formed by the plurality of partition walls 43a.

Since the active air flow by vortex directly contacts the surfaces of the plurality of partition walls 43a to maximize the number of air particles receiving heat, it is possible to effectively dissipate the heat sink 43 to cool the thermoelectric element 41.

Additionally, the heat sink 43 according to the exemplary embodiment of the present invention may control a plurality of partition walls 43a in a rod shape extending in a direction perpendicular to the floor in order to increase a heat radiation effect due to vortex formation.

The heat dissipation fan 47 and the heat sink 43 can be coupled and fixed by the device frame 46, and can also be stably coupled to the base plate 14 by the device frame 46.

The device frame 46 is connected to the heat sink 43 and the heat sink fan 47 in which the thermoelectric element 41 and the heat transfer layer 42 are coupled to support them firmly, thereby preventing rotation and external shock of the heat sink fan 47. This can prevent the durability from being lowered.

The device frame 46 may include a pair of frame side walls 46a extending in one direction, perpendicular to the floor, and parallel to each other.

In addition, a frame support wall 46b disposed between one pair of frame sidewalls and disposed on one side and the other side between the pair of frame sidewalls in the one direction may include a frame support wall 46b. You can.

The heat sink 43 may be disposed on the frame support wall 46b between a pair of frame side walls 46a.

That is, the side wall 43a of the heat sink 43 is placed on the frame support wall 46b, so that the heat sink 43 can be disposed between the pair of frame side walls 46a.

The frame support walls 46b are spaced apart from each other in the one direction.

The frame supporting walls 46b spaced apart from each other may form a hollow portion in the device frame 46 together with a pair of frame side walls 46a.

A heat dissipation fan 47 may be disposed in the hollow portion of the device frame 46.

Accordingly, the heat radiating fan 47 may spray or transfer air from the lower surface of the heat sink 43 to the plurality of partition walls 43a of the heat sink 43.

Next, the intake and exhaust structures in the water tank 10 according to the embodiment of the present invention will be described in detail with reference to FIGS. 7 to 10.

As described above, in order to perform heat dissipation of the heat sink 43 by the heat sink fan 47, an intake from the outside to the heat sink fan 47 and an exhaust structure from the heat sink 43 to the outside must be designed.

For example, the air delivered to the lower surface of the heat dissipation fan 43 on which the plurality of side walls 43a are formed by the heat dissipation fan 43 moves along the space between the plurality of side walls 43a to move the heat dissipation fan 43. It can be vented through openings formed on both sides.

In addition, unlike the heat sink 43 shown, even if it includes a rod-shaped partition wall perpendicular to the floor, a plate-shaped partition wall extending in one direction is disposed at a side edge of a pair of the heat sink 43 so that the plate-shaped partition wall is formed. It can be vented to openings on both sides that are not arranged.
