材料で植木鉢を成形して、低温から植物を保護している
。When growing potted plants indoors, the flowerpot is often placed outdoors. If you place flower pots outdoors during the winter or expose them to cold air for long periods of time, the plants will die due to the low temperatures. For this reason, conventionally, flower pots have been molded from a heat-retaining material such as foamed resin to protect plants from low temperatures.
発明が 決しようとする課題

抵抗力を失い枯死することが多い。Problems to be Solved by the Invention However, since conventional heat-retaining flowerpots are not equipped with heating means, plants exposed to severe cold often lose their resistance to low temperatures and die.
特に、熱帯植物は人工的に作られた温室内に配置されて

部が冷却され、枯死の原因となる。In particular, even when tropical plants are placed in an artificially created greenhouse, the temperature within the greenhouse is set as an average temperature suitable for many plants. Therefore, it cannot be said that it is possible to maintain a temperature sufficient to grow plants that have a suitable temperature higher than the average temperature in the greenhouse. Additionally, there are usually temperature differences between different parts of the greenhouse, which can result in low temperatures in some areas, which cools the root trunks of plants and causes them to wither.

定される。Means for Solving the Problems A plant insulation container according to the present invention includes a container made of a waterproof and non-conductive material, and a heating resistor fixed to the container. The container may be made of ceramic, plastic or metal. The container may also be formed from non-ferrous metals such as aluminum. The heating resistor is a non-metal heating element such as a thermistor or a metal heating element such as a nichrome wire. The heating resistor is formed as an intermediate layer within a container made of ceramic, or the heating resistor is fixed to the inner or outer surface of the container, and a waterproof layer is further formed on the outside of the heating resistor. The heating resistor is connected to a power source via a resistor, fuse, or varistor. A light emitting element is connected in series or in parallel to the heating resistor. The container has a side wall and a bottom wall provided below the side wall, and the heating resistor is embedded or fixed in the side wall or the bottom wall of the container.

非導電性の材料で被覆される。When an AC or DC power source is applied to the heating resistor, current flows through the heating resistor and it heats up. Therefore, the container to which the heating resistor is fixed is heated, and the container is heated to a temperature necessary for the growth of the plant. When a positive temperature coefficient thermistor is used as a heating resistor, a large current flows when the temperature of the heating resistor is low. For this reason, the temperature of the heating resistor rises and the electrical resistance value increases, so the current value does not increase in the increased temperature state. Therefore, the container is automatically maintained at a constant temperature at all times. Also, when nichrome wire is used as the heating resistor, it is covered with plastic or other non-conductive material.

Further, a fuse or a varistor is connected to the heating resistor to block or limit the current when an overcurrent flows through the heating resistor.

で確認することができる。In the above structure, when in use, the container 11 can be used as a flower pot, and a plant can be planted by directly inserting a pot into the container 11. Alternatively, a flowerpot with a plant planted therein may be placed inside the container 11. In this state, when the AC power supply 18 is turned on and a current flows through one electrode 13, the PTC thermistor 7-, and the POSISTOR 17, the PTC thermistor 12 is heated. Since the electrical resistance value of the PTC thermistor 12 increases as the temperature of the PTC thermistor 12 increases, the PTC thermistor 12 is maintained at a temperature that provides a balance between heating and heat radiation. That is, when the temperature of the PTC thermistor 12 is low, a large current flows and the PTC thermistor 12 is heated.
Conversely, when the temperature of the PTC thermistor 12 is high, the current is limited and heating of the PTC thermistor 12 is suppressed. Thereby, the container 1 can be heated to a temperature necessary for the growth of plants. Further, since the neon tube 21 lights up while the positive characteristic thermistor 12 is energized, the energization state can be visually confirmed.
