Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heater provided within the wall of a flower pot to warm the soil of the flower pot and the surroundings of the flower pot.

In recent years, home gardening, including ornamental plants, has become popular, but in winter, when the temperature drops, the soil inside the flowerpot also gets cold, which can cause plants to fail to grow or die.

Conventional methods to prevent this have been explored, such as exposing sunlight during the day and bringing it indoors at night, or building a greenhouse to overwinter, but the former method of sunlight exposure depends on the weather. It lacked certainty and required time and effort to move. The latter greenhouse method also had the disadvantage of high equipment costs.

The present invention aims to solve the above-mentioned drawbacks and provides a flowerpot with a heater that can heat the soil and the surroundings of the flowerpot using electric heat.

Hereinafter, one embodiment of a flower pot with a heater of the present invention will be explained with reference to FIGS. 1 and 2.

In the figure, (1) is a wall that constitutes a flower pot, (1a) is an inner wall, and (1b) is an outer wall. The inner wall (1a) and the outer wall (1b) are connected at the upper part, and have a heat radiation hole (2) at the connecting part and at the upper part of the outer wall (1b). Between the inner wall (1a) and the outer wall (1b) is a heater (4) wrapped in a heat-resistant insulating material (3). (5) is an electric wire that connects electricity to the heater (4). In other words, the outer wall (1b), inner wall (1a), and bottom surface (1c) are made of a plastic material with excellent heat and soil resistance. ) and the outer wall (1b). Then, when electricity is turned on to the heater (4), the heater (4)
becomes hot and warms the inner wall (1a) and outer wall (1b).

Since the soil for growing plants is packed inside the inner wall (1a), as the inner wall (1a) warms, the soil gradually warms as well. On the other hand, the outer wall (1b) is cylindrical and has a loop hole (heat radiation hole (2)) at the top, and the air heated by the heater (4) escapes through the heat radiation hole (2), due to the chimney effect. It can easily escape upwards and warm the leaves and branches.

The heat generating capacity of the heater (4) is small enough to prevent the soil from freezing, so power consumption is small and costs are low. The heat source is electricity, and if there is a power source nearby, it can be easily obtained via electric wire (5), and does not alter the soil or generate harmful substances that have a negative impact on plants.

The heater (4) is wrapped in heat-resistant insulating material (3) and installed to prevent it from falling on the inner wall (1a) of the flowerpot, so it will not be affected even if the flowerpot is watered or fertilized, and the flowerpot will not be affected by water or fertilizer. When moving or replacing existing plants, there is no problem even if you cover the soil a little.

Other embodiments and application examples of the heater-equipped flower pot of the present invention will be described below.

Figure 3 shows a flowerpot made of plastic with a heater (4) and a heat sink (6) embedded in the wall (1), and an electric wire (5) that connects the heater (4) to the flowerpot. A plug socket (7) is provided at the bottom of the socket so that the electric wire (5) can be attached or detached.

The heat sink (6) is made of a material with good thermal conductivity (for example, metal), and allows the heat generated by the heater (4) in the wall (1) to easily reach the leaves above the pot. A heat insulating material is pasted on the surface of the heat dissipation plate (6) to prevent damage caused by heat even if it comes into direct contact with the leaves and branches of plants.

As another example (not shown), the flower pot may be made of a double structure made of metal plates with good thermal conductivity, and a heater wrapped in insulating material may be provided between the walls, or a flower pot made of metal plates and a flower pot made of plastic or ceramic. A heater may be placed in the space between two flowerpots, such as a flower pot, in such a way that there is a gap in the wall. If flower pots are made of materials with good thermal conductivity, they can be heated almost evenly even if the heaters are sparsely placed.

Alternatively, grooves or the like may be provided on the inner surface of the flowerpot to replenish the air in the soil that decreases by warming the soil.

The heater (4) may be provided not only on the side wall of the flower pot, but also only on the bottom surface, or on both sides. Moreover, the shape, length, installation method, and arrangement method of the heater (4) are not limited, and may be determined depending on the size and shape of the flowerpot.

Also, depending on the degree of coldness, type of plants, etc., heaters (
A device that can adjust the temperature of (4) may be provided, or a device that can sense the temperature of the soil and automatically turn on and off the electricity of the heater (4) may be provided.

Allows for more precise temperature control of plants.

In addition, an indicator light is installed in a part of the flowerpot, and the heater (4)
If the power is turned on when the power is on, it will light up to let you know that the power is on, thereby preventing wasted power due to forgetting.

Another method of connecting electricity to the heater (4) is to provide an electrode on the underside of the flower pot, and a contact plate that can come into contact with the electrode of the flower pot on the shelf where the flower pot is placed, so that electricity is automatically turned on when the flower pot is placed on the shelf. The state may be changed.

The shape of the flowerpot containing the heater (4) may be round, square, etc., regardless of shape and size. If you arrange other flowerpots around a flowerpot with a built-in heater (4) and cover it with a cold-proof sheet such as a vinyl sheet, the inside of the sheet will be warm and you can prevent the cold from getting cold.

Since this invention incorporates a heater (4) within the wall (1) of the flower pot, the place where plants grow is the same as in conventional flower pots. The optimum arrangement and capacity of the heater (4) can be determined according to the shape and size of the flowerpot without requiring the effort of removing the heater (4) even in winter or summer. Since the heat source is electric, the temperature can be easily controlled, and since the heater (4) is protected within the wall (1) of the flower pot, it is safe to handle.

As explained above, this invention provides a heater within the wall of the flowerpot, and a device that connects electricity to the heater.When electricity is passed through the heater, the heater heats up.The heat warms the flowerpot, and the soil in the flowerpot and the flowerpot are heated. The warmth radiated from the tree is applied to the leaves and branches, protecting plants that are sensitive to cold from the cold.

Since the heater is built in specifically for the flower pot, it can be heated under optimal conditions, is easy to handle, and costs less, making it possible to make a flower pot with a heater that is useful for gardening in winter.
