10 and 11, the water temperature sensor 85 may sense the temperature of water stored in the water tank 10. The water temperature sensor 85 can detect the temperature of the water stored in the water tank 10 and input the detected water temperature value to the control unit C, and the control unit C uses the water temperature value input from the water temperature sensor 85. By doing so, the thermoelectric element 81 can be controlled.

The controller C receives the water temperature value from the water temperature sensor 85, and if the temperature of the water stored in the water tank 10 sensed by the water temperature sensor 85 is greater than or equal to the first set value, the thermoelectric element ( 81) can be activated.

Further, the control unit C may stop the operation of the thermoelectric element 81 when the temperature of the water stored in the water tank 10 detected by the water temperature sensor 85 is less than or equal to the second set value during the operation of the thermoelectric element 81. have. Here, the first set value may be a value higher than the second set value, and the second set value may be a value lower than the first set value.

Meanwhile, the thermoelectric element temperature sensor 81a may sense the temperature of the thermoelectric element 81. The thermoelectric element temperature sensor 81a may sense the temperature of the inner space 119 of the lower edge wall 11b. Hereinafter, the thermoelectric element temperature sensor 81a will be described as being limited to sensing the temperature of the inner space 119 of the lower edge wall 11b, but the thermoelectric element temperature sensor 81a senses the temperature of the inner space 119. Since it means that the temperature of the inner space 119 due to heat generated by the thermoelectric element 81 is sensed, the thermoelectric element temperature sensor 81a senses the temperature of the thermoelectric element 81, and thus is interpreted as the same meaning. Can be.

The thermoelectric element temperature sensor 81a may sense the temperature of the inner space 119 and input the detected temperature value of the inner space 119 to the control unit C, and the control unit C may perform the thermoelectric element temperature sensor 81a. The motor 82 may be controlled by using the temperature value of the internal space 119 input from.

The thermoelectric element temperature sensor 81a may be disposed between the bottom plate 12 and the base 18 of the water tank 10. The thermoelectric element temperature sensor 81a may be installed on the edge surface 117 protruding inside the lower edge wall 11b.

The control unit C receives the temperature value of the inner space 119 from the thermoelectric element temperature sensor 81a, and when the temperature of the inner space 119 is determined to be greater than or equal to the set value, the heat radiating fan 83 is rotated. The motor 82 may be operated to cool the thermoelectric element 81 and the heat sink 84.

In addition, when the temperature of the internal space 119 input from the thermoelectric element temperature sensor 81a during the operation of the motor 82 is less than the set value, the control unit C may stop the operation of the motor 82.

Referring to Figure 12, the control method of the companion animal water supply according to an embodiment of the present invention, the water temperature sensor 85 in the water temperature detection step (S1) detects the temperature of the water stored in the water tank (10). The water temperature sensed by the water temperature sensor 85 is input to the control unit C.

Thereafter, in the determination step S2, the controller C determines whether the water temperature detected by the water temperature sensor 85 is equal to or greater than the first set value. That is, in the determination step S2, the controller C determines whether the water temperature input from the water temperature sensor 85 is equal to or greater than the first set value.

As a result of the determination step S2, if the water temperature sensed by the water temperature sensor 85 is less than the first set value, the controller C determines that the temperature of the water stored in the water tank 10 is a temperature suitable for drinking by a companion animal, The logic may be returned to the water temperature sensing step (S1).

In addition, as a result of the determination step S2, if the water temperature sensed by the water temperature sensor 85 is greater than or equal to the first set value, the control unit C has a temperature at which water stored in the water tank 10 is difficult for companion animals to drink. It is determined that it has risen, and the thermoelectric element 81 can be operated. That is, in the thermoelectric element operation step (S3), the control unit (C) is the temperature at which the temperature of the water stored in the water tank 10 is difficult for the companion animal to drink if the water temperature detected by the water temperature sensor 85 is equal to or greater than the first set value. It can be judged that the temperature rises, and the thermoelectric element 81 can be operated.

When the thermoelectric element 81 is operated, the temperature of the bottom surface 12 of the water tank 10 in contact with the upper surface of the thermoelectric element 81 may be lowered because the temperature of the upper side becomes lower and the temperature of the lower side increases. , Accordingly, the temperature of the water stored in the water tank 10 may be lowered.

After the thermoelectric element operation step (S3), the controller C may determine whether the water temperature sensed by the water temperature sensor 85 is equal to or less than the second set value. That is, in the determination step S4, the control unit C may determine whether the water temperature detected by the water temperature sensor 85 is equal to or less than the second set value.

As a result of the determination step S4, if the water temperature detected by the water temperature sensor 85 is greater than the second set value, the water stored in the water tank 10 is not sufficiently cooled to be suitable for a companion animal to drink. Judging, the logic can be returned to the thermoelectric element operation step (S3).

In addition, as a result of the determination step S4, if the temperature detected by the water temperature sensor 85 is less than or equal to the second set value, the control unit C cools the water stored in the water tank 10 to a temperature suitable for drinking by a companion animal. Judging, the operation of the thermoelectric element 81 can be stopped. That is, in the thermoelectric element stopping step (S5), the control unit (C), if the temperature detected by the water temperature sensor 85 is equal to or less than the second set value, the water stored in the water tank 10 is cooled to a temperature suitable for drinking by a companion animal. It is determined that the operation of the thermoelectric soju 81 can be stopped.

Referring to FIG. 13, in the inner space temperature sensing step (S10), the thermoelectric element temperature sensor 81a senses the temperature of the inner space 119. The temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is input to the control unit C.

Thereafter, in the determination step S20, the control unit C determines whether the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is greater than or equal to the set value. That is, in the determination step S20, the control unit C determines whether the temperature of the internal space 119 input from the thermoelectric element temperature sensor 81a is equal to or greater than the set value.

As a result of the determination step S20, if the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is less than the set value, the control unit C generates less heat on the lower side of the thermoelectric element 81. It is determined that there is no need to discharge the heat of the internal space 119 to the outside, and the logic can be returned to the internal space temperature sensing step (S10).

In addition, as a result of the determination step S20, if the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is greater than or equal to the set value, the control unit C generates a lot of heat from the lower side of the thermoelectric element 81. It is determined that it is necessary to discharge the heat of the internal space 119 to the outside, and the motor 82 can be operated. That is, in the motor operation step (S30), if the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is greater than or equal to the set value, the control unit C generates a lot of heat from the lower side of the thermoelectric element 81. It is determined that it is necessary to discharge the heat of the internal space 119 to the outside, and the motor 82 can be operated.

When the motor 82 is operated, the heat radiation fan 83 coupled to the rotation axis of the motor 82 is rotated together with the rotation axis of the motor 82. The heat dissipation fan 83 blows air to the heat dissipation fin 845 contacting the lower surface of the thermoelectric element 81 when rotating. Therefore, the heat generated from the lower side of the thermoelectric element 81 is moved to the heat dissipation fin 845 and then heat exchanged with the air in the inner space 119, and then the water tank 10 through the vent 181 formed in the base 18. It can be discharged to the outside.

After the motor operation step (S30), the controller C may determine whether the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is less than the set value. That is, in the determination step S40, the control unit C may determine whether the temperature of the internal space 119 sensed by the thermoelectric element temperature sensor 81a is less than the set value.

As a result of the determination step S40, if the temperature of the inner space 119 sensed by the thermoelectric element temperature sensor 81a is not less than the set value, the controller C is not sufficiently cooled. Judging, it may return the logic to the motor operation step (S30).

In addition, as a result of the determination step S40, if the temperature of the inner space 119 detected by the thermoelectric element temperature sensor 81a is less than the set value, the temperature of the inner space 119 is sufficiently cooled. Judging, the operation of the motor 82 can be stopped. That is, in the motor stop step (S50), the control unit (C), the temperature of the inner space 119 sensed by the thermoelectric element temperature sensor 81a is less than the set value, the temperature of the inner space 119 is sufficiently cooled. It is possible to judge, stop the operation of the motor 82, and terminate the logic.

As described above, according to the companion animal water supply and the control method thereof according to an embodiment of the present invention, the temperature of the water stored in the water tank 10 using the thermoelectric element 81 can be maintained at a temperature that the companion animal can drink. .
