Description

Greenhouse humidity control device

The present invention utilizes the moisture absorption ability of porous activated carbon located at the upper part of the greenhouse to act as a dehumidifier for natural humidification by sunlight from the upper part of the greenhouse during high temperature drying and artificial greenhouse closure to increase the humidity during winter. Rather, it relates to a humidity control device for a greenhouse that can prevent the spread of pests and pests in the atmosphere of the greenhouse by using the sterilization effect of activated carbon.

In general, a greenhouse is a structure that maintains an appropriate indoor temperature for cultivating plants regardless of changes in the external environment according to the season, so that vegetables, fruits, crops, horticultural crops, etc. can be harvested regardless of the season .

Looking at the structure of such a greenhouse, holding pipes are installed at regular intervals in the ground, the pipes are fixed to the holding pipes across the holding pipes between the holding pipes, and transparent plastic or vinyl material or glass is installed on the outside of the pipe. installed and fixed

In relation to such a greenhouse, recently, a roof opening and closing type greenhouse that can easily open and close the roof of the greenhouse and can prevent deformation and damage caused by the closing of the roof while sealing the roof using a skylight has been registered in the Korean Patent Publication No. No. 10-1996626 has been proposed.

However, the items proposed in the domestic registration number 10-1996626, etc. are for greenhouse ventilation, and even if the continuous opening at high temperature becomes a ventilation function to reduce the rise in high temperature, it rather lowers the humidity to reduce the occurrence frequency of pests and diseases. High humidity is the cause, and when the outside temperature is low and ventilation is not possible to keep warm, there is no countermeasure for dehumidification. Most of the humid conditions when saturated steam particles are in a fog state provide good conditions for pathogen germination and invasion. There is no functional product, so development is urgently needed.

In addition, the humidification function of the inside of the greenhouse, proposed by the Korean Patent Publication No. 10-1879999, etc., is a method of spraying fine particles in the air. The function of humidifying the humidity in the air by increasing the moisture or dropping the worker's head in the greenhouse has a problem that the effect is weak and there is no dehumidifying function.

Due to the change in abnormal temperature, even with all the side windows of the greenhouse house open in midsummer, it is difficult to manage the temperature, so the number of farms installing fans is increasing. As a result, the product quality is lowered due to the occurrence of deformation and poor fertilization rate.
