Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing root rot used for culturing plants.

[0002]

2. Description of the Related Art For example, when culturing plants that are sensitive to environmental changes such as alpine plants, it is necessary to take measures to prevent the temperature of soil in a flower pot from excessively rising. As a countermeasure, a water storage tank is provided at the bottom of a flower pot for storing cooling water, and a water-cooled flower pot is used to cool the flower pot by evaporating the cooling water.

A conventional water-cooled flower pot has a water storage section for storing cooling water, a plant culture section for culturing plants, and a porous partition plate for separating the water storage section and the plant culture section.

[0004] In the water-cooled flowerpot having the above configuration, cooling water is stored in a water storage section.

[0005] By evaporating the stored cooling water, the temperature of the plant cultivation section is lowered, and an excessive rise in the temperature of the plant cultivation section is prevented.

[0006]

However, in a water-cooled flowerpot having the above-described structure, the temperature of the plant culture section can be lowered by cooling water, but most of the evaporated water is absorbed by the plant culture section. As a result, it is not possible to control the water content in the plant cultivation section, and thus there is a possibility of causing root rot in plants that prefer to dry.

The water-cooled flower pot requires management such as replenishing cooling water in the water storage section during cultivation of the plant. Since the amount of water inside cannot be checked from the outside, there is a possibility that the amount of cooling water in the water storage section is reduced and a desired cooling effect cannot be achieved.

[0008] In view of the above problems, the present invention provides a desired water content to a plant culture part, makes it possible to cool the plant culture part, prevents root rot of plants, and provides cooling water in a water storage part. An object of the present invention is to provide a plant culture device capable of confirming the amount of water.

[0009]

Means for Solving the Problems In order to solve the above problems and achieve the object, a plant culturing apparatus of the present invention is configured as follows.

[0010] The plant culturing apparatus of the present invention is provided with a plant culturing unit in which a plant is cultivated, disposed above, a water storage unit for storing water, and extending from an outer peripheral surface of the water storage unit. A water supply section for supplying water to the section, and a vent provided above the water storage section and between a water surface and a bottom of the plant culture section.

[0011] With the above configuration, the plant culturing apparatus sends desired water to the plant culturing section, allows the plant culturing section to be cooled, and confirms the amount of cooling water in the water storage section. .

[0012] The water supply unit may include a water amount indicating member indicating the amount of water in the water storage unit.

With the above configuration, the plant culturing apparatus can more surely confirm the amount of cooling water in the water storage section.

The vent may have an adjusting member for adjusting the opening area of the vent.

[0015] With the above configuration, the plant culturing apparatus enables the opening area of the vent to be adjusted even after the plant culturing apparatus is manufactured, and arbitrarily selects the amount of water to be sent to the plant culturing section. It becomes possible.

The plant culturing unit and the water storage unit may be
It is also possible that they are formed integrally.
