BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf for a pot having a heat-retaining function for heating and keeping the bottom of a pot for plant cultivation such as a flowerpot or a planter, in particular, carbon short fiber as a core wire. The present invention relates to a shelf for pots that uses a linear heating element in which a core wire is covered with an insulating coating.

2. Description of the Related Art In recent years, greenhouse cultivation of plants has come to be widely used as an individual hobby, not only for business use. In particular, an increasing number of people enjoy potted gardening by installing simple small greenhouses for home use under the eaves of houses or on the verandas of condominiums.

[0003]

In general, such a small-sized greenhouse does not have a heating facility from the economical point of view, and therefore the temperature difference between the daytime and the nighttime is large in the winter, and the greenhouse is nighttime. There is a problem that the soil floor temperature of the planters and flower pots installed inside the plant will drop significantly, adversely affecting the cultivated plants. Further, if the heating device is installed in the greenhouse, such a point can be solved, but the cost and maintenance cost such as electricity cost are high, and it is not practical as a simple type small greenhouse for home use of this kind.

Therefore, a main object of the present invention is a pot holder used in a greenhouse, which can efficiently heat the bottom of a pot for plant cultivation placed on the shelf plate and has a simple structure. Therefore, it is an object of the present invention to provide an economical shelf for pots that can maintain the temperature of pot soil at low cost and with little energy.

Still another object of the present invention is to ensure excellent thermal efficiency, mechanical strength and economy by using a linear heating element in which carbonaceous short fibers are coated with an insulating coating as a heating medium. The purpose is to provide a pot shelf that has a function to keep the pot soil warm.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, in the pot holder according to the present invention, there is provided a shelf (A) having a plurality of shelves (1) on which the pots (B) for plant cultivation are placed. On the upper surface or the lower surface of (1), a linear heating element (2) in which a carbon short fiber is used as a core wire (2a) and the core wire (2a) is covered with an insulating coating material (2b) is attached, and the linear heating element ( A lead wire (3) extending from 2) to the outside of the shelf is provided, and an outlet (4) is provided at the tip of the lead wire (3).

[0007]

[Function] The above-mentioned pot holder (A) is usually placed in a greenhouse for use. By connecting the lead wire (3) to the power source through the outlet (4), the linear heating element (2) is heated and the shelf board
(1) The bottom of the pot (B) for plant cultivation placed on the top is warmed, and the pot soil is heated and kept at a suitable temperature.

[0008]

Embodiments of the present invention will be described below with reference to the embodiments shown in the drawings. 1 and 2 show a first embodiment of the present invention, in which a reference numeral (A) shows a bowl shelf according to the present invention. The linear heating element (2) is attached to the upper surface of the shelf plate (1) of the bowl shelf (A) via a suitable stopper (5) at a predetermined interval.

In the linear heating element (2), as shown in FIG. 4, carbon short fibers are used as core wires (2a), and the core wires (2a) are woven or braided (2c) of heat resistant fibers. It is covered with a waterproof insulating coating (2b). The core wire (2a) is a bundle of short-back fibers, and has a large heat generation area, so that heat generation efficiency is good, and far infrared rays are emitted, so that heating efficiency is high.
It is also very effective in that it has excellent flexibility and strength and that a desired electric resistance value can be easily set.

Thus, the lead wire (3) is branched from the linear heating element (2) through the branch connector (6), and the outlet (4) is provided at the tip thereof. The outlet (4) may be a plug having a pair of insertion protrusions as shown in the figure, or may have an insertion hole into which the plug is inserted. Further, in this embodiment, the lead wire is
Adjustment dial integrated with the middle part of (3) or outlet (4)
A voltage converter (8) including (7) is provided.

In the present embodiment, the linear heating element (2) is arranged on the upper surface of the shelf board (1), and a net-like or porous plate (9) which easily conducts heat is provided above the linear heating element (2). Although it is formed so that the bowl (B) is placed on the (9), the plate (9) is omitted, and the bowl (B ) May be placed. See also FIG.
As shown in, a large number of holes (1a) ... are formed in the shelf plate (1),
The linear heating element (2) may be formed on the lower surface of the shelf plate (1).

The above-mentioned shelf (A) for pots is usually placed in a greenhouse for use. By connecting the lead wire (3) to the power supply through the outlet (4), the linear heating element (2) is heated,
The bottom of the pot (B) for plant cultivation placed on the shelf (1) is warmed, and the pot soil is heated and kept at a suitable temperature. Also voltage converter
By changing the voltage flowing to the linear heating element (2) with the adjustment dial (7) of (8), the temperature can be arbitrarily adjusted according to the outside air temperature and the type of plant to be cultivated. . Regarding the temperature of the soil floor, the optimum temperature can be judged from the feel by inserting your fingers into the soil, but it is more convenient to install a thermometer that can measure the soil temperature.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, the voltage converter (8) shown in the above embodiment can be omitted. In addition, the present invention has the constitutional requirements, achieves the object of the present invention, and can be appropriately modified and implemented within a range in which the following effects are exhibited.

[0014]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it is possible to effectively warm the bottom of the pot for plant cultivation placed on the shelf plate and achieve the heat retention of the pot soil temperature. However, in particular, in the present invention, the use of a durable linear heating element with good heat efficiency in which carbonaceous short fibers are covered with an insulating coating and direct heating to the bottom of the bowl reduces the size. Power consumption can be effectively maintained for a long period of time, and radiant heat emitted from the linear heating element can also be expected to retain the greenhouse effect. It has various excellent effects that it can be manufactured at low cost because it has a simple structure.
