Solar heat utilizing planter

Abstract

The invention provides a solar heat utilizing planter which enables the good heat conduction of the soil in the planter and heat accumulation materials, and can prevent the extreme reduction of the ground temperature in winter and can suppress the raising of the ground temperature in autumn, as well as has the functions of heat insulation, external temperature isolation, and capability of receiving sunlight and directly storing the solar heat with the heat accumulation materials. The heat accumulation materials (2) are accumulated in the side wall (1). A heat conduction surface (7) for exchanging heat between the heat accumulation materials (2) and the soil (6) in the planter is arranged on the inner surface of the side wall (1). The heat accumulation materials (2) are formed in a free replacing manner. Furthermore, the composite resin materials having the properties of low heat conduction rate and light transmission form the side wall (1), and the composite resin materials have an air layer (4) for the thermal insulation of the accommodating part (3) of the heat accumulation materials (2).

Description

technical field [0001] The present invention relates to a planter, and in more detail, to a planter utilizing solar heat formed to protect roots of plants such as vegetables and flowers from the cold of winter and the heat of summer. Background technique [0002] Conventionally, as such a planter, there is a planter described in Patent Document 1, for example. [0003] The feature of this conventional product is that in order to protect the plants from the cold in winter, the flower pot is formed into a double-shell structure, and the latent heat storage material is enclosed in the hollow part of the double-shell, so that the volume of the lower part of the hollow part is large. . [0004] However, among vegetables, for example, there are cold-resistant varieties and heat-resistant varieties. In this case, even for cold-resistant vegetables, if the temperature of the root region drops to around 0°C, the activity of the roots will decrease, and the roots may die due to this...

AI Technical Summary

Problems solved by technology

[0012] However, this kind of planter cannot cut off the outside air temperature to prevent the ground temperature from decreasing in winter and rising in summer

[0013] In other words, this existing product cannot directly introduce sunlight to use solar heat for the rise of ground temperature in winter when the solar heat energy becomes smaller
