DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an animal and plant breeding apparatus used for breeding and ornamenting animals and plants such as tropical fish.

[0002]

2. Description of the Related Art Among the animal and plant breeding apparatuses as described above, for example, an aquarium for aquarium fish is widely used for ornamental and breeding of tropical fish. The temperature of the water in the aquarium must be adjusted according to the size of the ornamental fish.

As such a heating device, there has been proposed a heating device for heating a bottom plate of a water tank body, instead of the conventional underwater heater method. For example, it has been proposed to heat the bottom plate of the water tank body with a heater, or to provide an electromagnetic heater near the bottom plate of the water tank body so that the bottom plate itself is heated by the high-frequency induction effect of the electromagnetic heater. I have.

[0004]

However, since the bottom plate of the conventional water tank body is flat, a stress is generated at the joint between the bottom plate and the side plate due to a temperature change. That is, the bottom plate tends to expand and contract with the temperature change, but the peripheral portion of the bottom plate cannot be expanded and contracted because it is fixed by the side plate such as the glass plate of the water tank body. As a result, the bottom plate and the side plate A stress is generated at the junction with the substrate. And
When the stress is large, it is expected that the joint between the bottom plate and the side plate is disconnected or that the bottom plate and the side plate are distorted.

The present invention has been made in view of such technical background, and provides a highly reliable and durable animal and plant breeding apparatus capable of absorbing expansion and contraction of a bottom plate caused by a temperature change. Aim.

[0006]

In order to achieve the above object, according to the present invention, a side plate made of glass is in contact with a peripheral portion of a bottom plate.
A plant and animal breeding apparatus that adjusts the temperature inside the apparatus body by heating or heating the bottom plate of the combined animal and plant breeding apparatus main body, wherein the bottom plate of the animal and plant breeding apparatus main body is generated on the bottom plate with a change in temperature. It is characterized in that unevenness for absorbing expansion and contraction is provided.

According to this, the expansion and contraction of the bottom plate caused by the temperature change can be absorbed by the undulations of the unevenness provided on the bottom plate.

The unevenness for absorbing the expansion and contraction generated on the bottom plate due to the temperature change is preferably formed in a substantially circular or elliptical corrugated shape in plan view. According to this, all the expansion and contraction in the plane direction of the bottom plate can be absorbed by the unevenness.

1 to 5 show an embodiment in which the present invention is applied to an ornamental fish tank.

The ornamental fish tank includes a base (1) provided with an electromagnetic heater (6) and the like, a water tank body (2) provided above the base (1), and a water tank body ( And electrical equipment (3) such as a lighting device provided further above 2).

The base (1) is a hollow rectangular parallelepiped base made of a synthetic resin having a water tank main body fixing rib (1a) formed at a peripheral edge of the upper surface, and a contact terminal ( 4) is protruded. In addition, as shown in FIG.
Switching power supply (5) and electromagnetic heater (6) inside
Is provided.

The switching power supply (5) converts a 100V AC voltage for home use or the like to a 24V DC voltage. The switching power supply (5) is provided with a power supply cord (7) for obtaining electric power, and the contact terminal (4) and an electric wire ( 8). Therefore, the plug (7a) of the power cord (7)
Is plugged into an AC outlet, 100 V AC power is supplied from the AC outlet to the switching power supply (5), and the switching power supply (5) converts the voltage to DC 24V there.

Is also bridged with a spring type pressure sensor (10) provided on the upper surface of the base, and when the water tank main body (2) is placed on the base upper surface and pressure is applied to the sensor (10), as usual. Electric power is supplied to the contact terminal (4) and the electric heater (6). However, the water tank body (2) is removed from the upper surface of the base, and the pressure applied to the sensor (10) disappears.
If 0) protrudes due to the spring force, the power is turned off and the supply of power is stopped.

The electromagnetic heater (6) is also called IH, and generates heat on the stainless steel bottom plate (11) of the water tank body (2) by the principle of high frequency induction heating. That is, magnetic field lines are generated by passing a high-frequency current through a circular coil provided inside the electromagnetic heater (6), and the magnetic field lines are passed through the bottom plate (11) to cause the bottom plate (1).
An eddy current is generated in 1), and the bottom plate (11) itself is heated by electric resistance at that time. Therefore, the electromagnetic heater (6) with the water tank main body (2) placed on the upper surface of the base (1)
When the is driven, the bottom plate (11) generates heat, and the generated heat adjusts the water temperature in the water tank. In particular, the electromagnetic heater (6) has a high thermal efficiency, does not generate a flame, and allows fine temperature adjustment by adjusting the amount of current, so that the water temperature adjustment important for ornamental fish can be accurately performed and is convenient. .

In this embodiment, the bottom plate (11) is made of a stainless steel plate, but may be made of another magnetic material. Alternatively, the bottom plate (11) may be made of a non-magnetic material having a high thermal conductivity, such as an aluminum plate, and a stainless steel plate may be formed on the back surface. A magnetic body such as a plate may be provided. In addition, the bottom plate (1
