Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus capable of automatically controlling and controlling indoor temperature and ground temperature in a nursery house.

[0002]

2. Description of the Related Art As a conventional technique, there is a nursery house in which a self-controlled heater is arranged between the nursery pot and the ground, which was made by the present inventors. (Application filed on July 9, 1990, 1990 Patent Application No. 181360).

According to the present invention, the seedlings at the ends in the nursery house can retain the temperature suitable for growth, like the seedlings in the center.

Further, when the room temperature of the seedling raising house is extremely lowered in winter, a hot water pipe or a hot air duct is provided in the seedling raising house to heat the temperature inside the seedling raising house.

[0005]

In the invention of the above application, there is a problem that the ability to automatically sense the room temperature and the ground temperature and the ability to lower the room temperature of the nursery house are inferior.

The hot water pipe or the hot air duct provided in the nursery house can achieve the purpose of heating when the temperature is low, but cannot be used when the room temperature becomes high. There was a point.

When the room temperature of the nursery house becomes high, if the nursery house is made of vinyl, the hem of the vinyl curtain must be rolled manually, and at night, the temperature will rise. Since it lowers, the hem of the vinyl curtain must be lowered, and the hot water pipe or the hot air duct must be operated when necessary, but this is a labor-intensive task, so the labor is very difficult. It was something.

Furthermore, since the temperature inside the room affects the growth of the seedlings, in some cases the day may have to be monitored almost all day, and from this point as well, the labor is terrible. There was a problem of a great burden of labor under the declining population and aging population.

Therefore, the present invention makes it possible to automatically control and monitor the room temperature and the ground temperature in the nursery house even if the season becomes cold or warm, so that the seedlings in the nursery house can be managed. The purpose is to reduce the labor of people involved in training.

[0010]

In order to achieve the above-mentioned object, an automatic monitoring control device in a nursery house according to the present invention comprises:
In a nursery house in which a self-controlling heater is placed between the seedling pot and the ground, an automatic control device is provided in the seedling raising house in the previous period, the self-controlling heater is connected to this automatic control device, and further in the nursery house. An indoor air temperature sensor, a ground temperature sensor, and a forced ventilation device are provided, and the indoor air temperature sensor, the ground temperature sensor, and the forced ventilation device are connected to the automatic control device.

An outside air temperature sensor is provided in the nursery house.
It is preferable to provide a heating device and / or a humidifying device and connect them to the automatic control device.

Further, a circulation fan may be provided in the nursery house.

[0013]

The indoor air temperature sensor detects the temperature inside the room and sends a signal to the automatic control device, and the ground temperature sensor detects the soil temperature and sends a signal to the automatic control device. Detecting the temperature, a signal is sent to a forced ventilation device and a self-controlled heater to keep the room temperature and soil temperature of the nursery house at a set temperature, and these are operated.

Further, the outside air temperature sensor, the heating device and / or the humidifying device are operated. Then, the circulation fan is operated as needed.

The forced ventilation device comprising a damper and a fan operated by an automatic control device works such that the damper sucks the outside air and the fan sends out the indoor air to the outside. Works to lower

Further, the self-controlled heater operated by the automatic controller functions to raise the room temperature and the ground temperature to the set temperature.

Further, when the self-controlled heater cannot raise the room temperature sufficiently, the warming device works by the automatic control device to raise the room temperature to the set temperature, and the humidifying device works by the automatic control device to make the room temperature higher. Humidity can be adjusted to the set humidity.

If an outdoor air temperature sensor is provided, the outdoor temperature can be sensed by the automatic control device, and the room temperature and ground temperature can be set and adjusted even better.

Further, by operating the circulation fan, it is possible to average the temperature without stagnation of the air in the nursery house.
