The water temperature control device described above has the effects of reducing the cost by applying a general-purpose remote control code and preventing continuous transmission of the cooling operation command code and the operation stop command code.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG. (Embodiment 1) FIG. 1 shows an outline of a water temperature control device. In FIG. 1, 1 is a water tank for holding, for example, appreciation fish, 2 is a water temperature control device control unit, and a water temperature sensor 3 is for water temperature in the water tank. Upon detection, the display unit 5 displays the set temperature, the operation unit 6 is composed of a switch for operating the set temperature, etc., and the transmitter 7 transmits the remote control code of the air conditioner 8. Reference numeral 9 is a remote control code receiver of the air conditioner 8.

FIG. 2 is a block diagram showing a circuit configuration of a water temperature control device according to an embodiment of the present invention.

FIG. 3 is a flow chart showing the operation of the controller of the water temperature controller according to the embodiment of the present invention.

Next, the operation of the water temperature control device will be described with reference to FIGS. 1 to 3.

First, the target value of the temperature of the water tank 1 is set from the operation unit 6. The target value is displayed on the display unit 5. Next, the water temperature sensor 3 measures the current water temperature in the water tank 1. Then, the water temperature control device controller 2 compares the target temperature displayed on the display unit 5, the temperature measured by the water temperature sensor 3, and the temperature measured by the water temperature sensor 3.

When the measured temperature is higher than the target temperature, the command code for the cooling operation is transmitted to the remote control code receiver 9 of the air conditioner 8 through the transmitter 7. Also,
When the measured temperature is lower than the target temperature, the transmitter 7 transmits a command code for stopping the operation to the remote controller code receiver 9 of the air conditioner 8.

The command code transmitted in these cases is a code of a remote controller using general infrared rays as a communication means, and the various remote controller codes use the same remote controller code corresponding to the air conditioner 8. However, since it is not necessary to always transmit the same code as the remote control code, the air conditioner ON flag is used as shown in the flow chart of FIG. 3 so as not to continuously transmit the cooling operation command code and the operation stop command code. .

Next, the remote control code receiving section 9 of the air conditioner 8 receives the remote control code from the transmitting section 7, and the air conditioner 8 performs cooling operation or operation stop.

As a result, the water tank 1 is cooled during the cooling operation of the air conditioner 8, the water temperature in the water tank 1 is lowered, and the air conditioner 8 is cooled.
However, when the operation is stopped, the aquarium 1 can be controlled to a temperature range that is comfortable for the appreciation fish.

The above operation is performed by circulating the blocks as shown in FIG. As described above, in the first embodiment, the basic information for controlling the water temperature of the water tank 1 is the water temperature sensor 3
It is the current water temperature in the water tank 1 measured by.

(Embodiment 2) In FIGS. 1 to 3, a room temperature sensor 4 is installed around the water tank 1 to detect the room temperature around the water tank 1, and the basic information for controlling the water temperature of the water tank 1 is room temperature. It is a means for indirectly estimating the current water temperature in the water tank 1 from the room temperature measured by the sensor 4 and controlling it.
In other words, it is a control means for cooling the water tank 1 when the room temperature around the water tank 1 is lowered by the cooling operation of the air conditioner 8 and preventing the air conditioner 8 from affecting the room temperature around the water tank 1 by stopping the operation of the air conditioner 8. .

This means is suitable when the present water temperature in the water tank 1 is not directly measured and when a plurality of water tanks 1 are simultaneously controlled by a single temperature controller.

From the above description, it is also a preferable means to use the water temperature sensor 3 and the room temperature sensor 4 together to perform fine water temperature control.

[0023]

As described above, according to the present invention, the temperature in the water tank can be optimally controlled by utilizing the air conditioner in the vicinity without the need for a dedicated device for cooling the water in the water tank. This has the advantageous effect of protecting appreciation fish from rising water temperatures and reducing capital investment in tanks.
