Abstract

【課題】観葉植物の育成における、水やりの時期について一般の方はなかなか判断ができない。このため水分不足で枯らせてしまう又、水分過多での根腐れ等をおこしてしまうとの問題があった。このため簡易に水やり時期を知らせてくれるものを提供する。
【解決手段】植物の育成に大切な「水やり」作業に関わる、水やりの判断をより正確で簡単にするために、土中水分が電気を通し、その水分量が少なくなるに従って電気抵抗値が上がることを利用し、土（用土）の違いによる感度の調整を可変抵抗を変えることで行い、植物によって異なる土中水分（土湿度）の値を各環境に合わせ変更することが可能であり又、自分流の水やり方式ができる。
【選択図】なしAn object of the present invention is to make it difficult for an ordinary person to judge the timing of watering in growing a houseplant. For this reason, there has been a problem that the water is withered due to insufficient water, and root rot or the like is caused by excessive water. For this reason, what simply informs the time of watering is provided.
[MEANS FOR SOLVING PROBLEMS] In order to make the judgment of watering related to the “watering” work important for growing plants more accurate and simple, the soil water conducts electricity and the electric resistance value decreases as the water content decreases. It is possible to change the value of soil moisture (soil humidity) according to each environment by adjusting the variable resistance to adjust the sensitivity according to the difference in soil (land medium), taking advantage of the fact that the soil rises. You can also create your own water style.
[Selection diagram] None

Description

本考案は、観葉植物の屋内育成における、水やり時期をキャラクター等に内蔵したＬＥＤランプにより、水分量が少なくなったとき点滅させ水やり時期を知らせる簡易表示機即ち水やりセンサーに関するものである。 The present invention relates to a simple display device, i.e., a watering sensor, which flashes when the amount of water is low by an LED lamp having a built-in character or the like in the indoor growing of houseplants to notify the time of watering.

従来のこの種センサーは、全般的に土湿度（土中水分）量を計測するものがほとんどであり、植物用に作られている物はまれである。又植物用のものであっても大掛かりな装置と成っており、家庭用の観葉植物の育成のための「水やり」には、下記の（イ）（ロ）（ハ）の点で不十分である。
（イ）構造上、用土、または、植物の種類によって感度調節を簡単にできない。
（ロ）水分量の測定値を個別に植物のタイプに当てはめて換算が必要となる。
乾き等の植物の種類で異なり、適正水分量がわからない
（ハ）観葉植物育成のための土（用土）の湿度は、各家庭において異なる。
従来のものでは、土中水分量は、測定不可能である。Most conventional sensors of this type generally measure soil humidity (moisture in soil), and rarely are made for plants. Also, it is a large-scale device even for plants, and it is not sufficient for “watering” for growing houseplants for home use in the following points (a), (b), and (c). It is.
(A) Due to the structure, sensitivity cannot be easily adjusted depending on the type of soil or plant.
(B) It is necessary to apply measured values of water content individually to plant types and convert them.
It differs depending on the type of plant such as dryness, and the amount of moisture is not known. (C) The humidity of soil (land medium) for fostering houseplants differs in each household.
Conventionally, the soil moisture content cannot be measured.

本考案は、植物の育成に大切な「水やり」作業の指針となるもので、水やり時期の判断をより正確且つ簡単にするために、土中水分が電気を通し、その水分量が少なくなるに従って電気抵抗値が上がることを利用し、土（用土）の違いによる感度の調整を可変抵抗を変えることで行い、植物によって異なる土中水分（土湿度）の値を各環境に合わせ変更することが可能であり又、自分流の水やり方式ができるようにしたものである。 The present invention is an important guideline for "watering" work for growing plants.To make the judgment of watering time more accurate and simple, the soil water conducts electricity and the water content is small. Taking advantage of the fact that the electric resistance value increases as it becomes available, the sensitivity is adjusted by changing the soil (land medium) by changing the variable resistance, and the soil moisture (soil humidity) value that differs for each plant is changed according to each environment. It allows you to do your own water style.

本考案の一例を図面について説明する。
（イ）基本的な構造は、電極２と電極３の二つの電極を平行に設置し、その電極間を土（用土）１の種類による通電状態に合わせて、最適な電極間隔とし、直接通電されないようにして電気コード１０を介して電源部（電池）６に接続する。
（ロ）電極は棒パイプ形状などの土壌に挿入しやすいものとする。
（ハ）電極２と電極３のそれぞれに、電気コード１０をつけ、電気抵抗測定回路７に接続し、これを例えばキャラクター人形などのケース内に一体的に収容する。
（ニ）土中に電極２と電極３を差し込み、抵抗測定回路７の可変抵抗などを調整し、土中水分量が目的の所定値になるまではＬＥＤ５が点灯しないように調節する。
以上（イ）（ロ）（ハ）を有機的に結合した水やりセンサを提供する。An example of the present invention will be described with reference to the drawings.
(A) The basic structure is that two electrodes, electrode 2 and electrode 3, are installed in parallel, and the interval between the electrodes is adjusted to the optimum electrode spacing according to the type of energization depending on the type of soil (land medium) 1, and direct energization is performed. To the power supply unit (battery) 6 via the electric cord 10 so as not to be connected.
(B) The electrode shall be easy to insert into soil such as a rod pipe shape.
(C) The electric cord 10 is attached to each of the electrodes 2 and 3 and connected to the electric resistance measuring circuit 7, which is integrally accommodated in a case such as a character doll.
(D) The electrodes 2 and 3 are inserted into the soil, and the variable resistance of the resistance measuring circuit 7 is adjusted so that the LED 5 does not light until the soil moisture content reaches a target predetermined value.
The present invention provides a watering sensor in which (a), (b), and (c) are organically combined.

本考案は、以上の構造であるから、これを使用するときは、図３のように、対象の植物８が植えられた土（用土）に本装置の電極２，３を差し込んでおくだけで、装置に内蔵された電池６から両電極間を通して土壌に電圧が印加され、その通電抵抗が電気抵抗回路７で検知される。この抵抗が所定値以上となったときＬＥＤランプ５が点灯または点滅するので、これによって植物育成ににおいて重要な「水やり」の時期をより簡単且つ確実に判断できる。 Since the present invention has the above structure, when it is used, as shown in FIG. 3, the electrodes 2 and 3 of the present apparatus are simply inserted into the soil (media) in which the target plant 8 is planted. Then, a voltage is applied to the soil from the battery 6 built in the device through both the electrodes, and the current-carrying resistance is detected by the electric resistance circuit 7. Since the LED lamp 5 is turned on or blinks when this resistance becomes equal to or higher than a predetermined value, it is possible to more easily and reliably determine the timing of “watering” which is important for plant growth.

なお、本考案の実施に当たって次の如きことができる。
図３の様にＬＥＤランプをキャラクタ人形の目の部分に装備しておき、観葉植物の近くに本考案の装置を設置し、土中の水分が乾燥しその通電抵抗が所定の電気抵抗値を超えた場合キャラクターの目部分が点滅発光するように構成する。又は同時に発音体を用いて発音しても達成することができる。In implementing the present invention, the following can be performed.
As shown in Fig. 3, an LED lamp is installed in the eyes of the character doll, and the device of the present invention is installed near houseplants. The eye portion of the character blinks and emits light when it exceeds. Alternatively, it can also be achieved by sounding using a sounding body at the same time.
