Description

[0001] The present invention relates to a water temperature control device for a fish tank,

The present invention relates to a water temperature regulating device for a fish tank, and more particularly, to a water temperature regulating device for a fish tank, which is compact in size and can selectively facilitate cooling and heating, minimizes heat travel path, And more particularly, to a water temperature controller for an aquarium which can be efficiently operated.

Generally, aquariums such as aquariums and aquariums for growing fish stocks should maintain a suitable temperature environment for growth depending on the characteristics of each species.

For this purpose, a conventional heating heater such as a nichrome wire is wrapped in quartz glass and directly precipitated in water in a water tank to heat water. However, the glass of the heating element may be broken, and there is a risk of electric shock to the fish body due to a short circuit.

However, in the case of changing fish from a tropical fish to a cold fish in an aquarium, existing heaters are no longer available, and a cooling system must be purchased separately. In the opposite case, the fish in the aquarium should be changed from cold fish to tropical fish The existing cooling system will be useless, and the heater must be purchased separately.

In addition, even if the aquarium fish in the fish tank is not changed, it may be necessary to heat the fish tank to raise the water temperature in order to maintain the water temperature within a certain range according to the ambient temperature change, or to cool the water in the fish tank to lower the water temperature. There is a burden to install both the cooling device and the heater.

In addition, in the case of the heater, most of the heater rods are installed so as to be submerged in the fish tank, so that it is possible to cause a short circuit due to the damage of the wire covering or insulation failure.

In addition, there is a problem that it is difficult to install the heater rod in a small tank having a large size and a large installation area because of a general heater rod.
