Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a horticultural heating unit used for heating potted plants used in general household and commercial horticulture.

BACKGROUND OF THE INVENTION In recent years, home gardening has become popular, and it has become possible to enjoy flowers and trees all year round. However, in order to see tropical plants in winter or in cold regions, it was necessary to warm the surrounding area with a greenhouse or heater. A conventional flower pot consists of a flower pot 1 shown in Fig. 2 with a hole in the bottom, a plastic net 10 to prevent ± from coming out of the hole, pieces of porcelain, cobblestones 3, ± 4, and a dish 6 as a water receptacle. In the case of plants that do not like the cold, they are warmed from their surroundings using greenhouses or heaters.

Problems to be Solved by the Invention However, such a conventional configuration requires equipment to heat a large area in winter and in cold regions, and it is difficult to create such a space for people living in rented houses, ahats, etc. This is a difficult situation.

Furthermore, there are many cases in which plants that are being cultivated in ordinary households wither due to sudden cold weather. Another drawback is that only a limited number of plants can be grown at a certain temperature, which is one of the reasons behind the slow progress in expanding popular gardening.
ing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heating element unit using a positive temperature coefficient thermistor, which is attached to the inside bottom of a cup-like shape so that it can be easily installed at the inside bottom of the flower pot. By applying voltage through a lead wire drawn out from the drainage hole and heating the flowerpot from within, the roots and stems of the plants are warmed, allowing them to germinate and grow.

In addition, by replacing the heating element unit with a positive temperature coefficient thermistor having a different switching temperature (Curie's temperature), the heating element unit can easily change the amount of heat and select the temperature necessary for growing plants.

Function The present invention has the above-mentioned configuration, and since the positive temperature coefficient thermistor has a self-control function to obtain a constant temperature even though the full voltage is applied, the plant is constantly heated at a selected temperature, thereby fully promoting the germination and growth of the plant. The overall purpose is to drain excess water and prevent the soil from flowing out.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention, in which a heating element unit 6 is pasted with adhesive to the bottom of a metal cup 7, which is placed upside down on the bottom of a flower pot 1. Pull out the lead wire 8 of the heating element unit from the water drain hole so that it can be energized. ・Inside the flower pot 1, be careful not to get too close to the metal cup 7 to which the heating element unit 6 is attached. and fill in tulip bulb 9.

Insert thermometer 2 into the soil, turn on the electricity, and pour about a cup of water into each flowerpot. Even in an unheated room where the ambient temperature is -1Q°C to +6°C, it reaches 4000 in a few hours.

However, if all moisture is removed, the temperature will be 6°C below the ambient temperature.
It was only a little above 100 degrees, and I had to replenish the water to keep it from drying out. Under these conditions, the seeds were able to germinate after one month.

At the same time, for comparison, no germination occurred in a flowerpot without a heating element unit. When we dug out the bulbs and observed them, we found that there were no signs of germination at all, and it was clear that there was a difference in growth.

Effects of the Invention As described above, according to the present invention, it is possible to provide a temperature that sufficiently promotes germination even in sub-zero temperatures, and by freely selecting the switching temperature of the positive characteristic server, it is possible to adjust the temperature to suit the desired plant. You can easily change the temperature. Moreover, it does not require a large space like a greenhouse, and you can enjoy the sounds of gardening with low electricity costs.
