(57) [Summary] [Purpose] The purpose of the present invention is to obtain a grafted seedling curing device that can prevent the danger of life even if an operator is trapped inside the warehouse because the door cannot be opened or closed. [Constitution] In a graft seedling curing device for curing grafted seedlings by circulating conditioned air, the graft graft seedling curing device is provided with an emergency switch for setting environmental conditions suitable for human beings in the cabinet.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graft seedling curing device for curing grafts by circulating conditioned air.

[0002]

2. Description of the Related Art A grafted seedling curing device for curing grafted seedlings by circulating conditioned air in a refrigerator is known.

[0003]

The grafted seedling curing device for curing grafted seedlings by circulating the air-conditioned air as described above is used by a worker to activate a ventilation fan before entering a warehouse and to cap an intake port inside the warehouse. It is designed to be detached for work. However, the conventional environment of this type cannot change the environment (temperature, humidity) inside the refrigerator. Therefore, when the doors cannot be opened / closed and the worker is trapped inside the warehouse, if the operator forgets to remove the cap of the intake port or forgets to operate the ventilation fan before entering the warehouse, there is a possibility of oxygen deficiency. is there. or,
Since the temperature and humidity cannot be adjusted inside the refrigerator, it may become hot and humid. Therefore, it is an object of the present invention to provide a graft seedling curing device that can prevent the danger of life even if the worker is trapped in the refrigerator due to the opening / closing of the door.

[0004]

SUMMARY OF THE INVENTION The present invention provides the following grafting and seedling curing device for achieving the above object. That is, in the grafted seedling curing device for curing grafted seedlings by circulating conditioned air, the grafted seedling curing device is characterized in that an emergency switch capable of setting environmental conditions suitable for humans is provided in the cabinet. .

[0005]

[Operation] Even if the entrance / exit door of the grafted seedling curing device cannot be opened / closed and the worker is trapped inside the warehouse, the emergency switch is still inside the warehouse. By operating this, you can switch to environmental conditions suitable for humans. You can work safely because you can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. First, the graft seedling curing device will be described. In FIGS. 3 and 4, a graft seedling curing device comprises a heat insulating panel (1) forming a main body, an air-conditioning chamber and a duct portion (2) which are partitioned by the inside thereof, and a seedling storage chamber (3) inside thereof. ,
On a vertical wall (14) of a duct part (2), a dolly (8) equipped with casters (7) to which shelves (6) for mounting grafted seedlings (4) in cell trays (5) are placed. It is composed of a perforated plate (15) as an attached air blowing portion, an opening (16) as a lower blowing portion, a fan (9) for circulating conditioned air, a fluorescent lamp (10) and the like. A cleaning coil (17), a heater (18), a humidifier (19), a temperature sensor (20) and a humidity sensor (2
1) and the like are provided. A door (11) and a control panel (12) are provided in front of the seedling storage chamber (3), and a refrigerator unit (13) is provided on the ceiling.

Now, the trolley (8) having grafted seedlings on all shelves is carried into the accommodation chamber (3), and the refrigerator unit (1
3), cleaning coil (17), heater (18),
The humidifier (19), the fan (9), etc. are operated to blow out the conditioned air from the perforated plate (15) and the opening (16) of the vertical duct (2a). When the air is blown out in this way, the air circulates as shown by the arrows in FIG. 3, the temperature sensor (20) and the humidity sensor (21) detect the temperature and humidity of the circulating air, and the control panel (12) Various devices are automatically controlled so that the temperature and humidity inside the seedling storage chamber (3) are controlled to a desired temperature and humidity. However, the environment (temperature, humidity) inside the refrigerator cannot be changed from the inside.

By the way, in order to ventilate the inside of the storage, the ventilation fan is operated before the storage and the cap of the intake port inside the storage is removed, but if the operation is forgotten before the storage, the entrance / exit door of the graft curing device cannot be opened / closed. Thus, if the worker is trapped in the refrigerator, there is a possibility that the worker will be in an oxygen-deficient state.

The present invention is to improve such a point, and an emergency switch (24) capable of changing over to environmental conditions suitable for human beings is provided in the refrigerator, and the position in the refrigerator is set at the entrance door (11). It is provided next to the as shown in FIG. However, the switch is waterproof, and one that does not leak is used.
The mounting position should be above the upper end of the dolly (8) and within the reach of workers. In FIG. 2, a ventilation fan (22) and an automatic intake shutter or valve (23) instead of a cap are provided on the back side opposite to the front side as in FIG. Ventilation fan (22)
Is the discharge side, automatic intake shutter, or valve (23)
Is the inhalation side. Therefore, when the entrance / exit door (11) of the grafted seedling curing device cannot be opened and closed and the worker is trapped in the refrigerator, the ventilation fan and the intake port are automatically operated by the operation of the emergency switch (24), and the alarm device is activated. With
Switch to environmental conditions suitable for humans. That is, the temperature is 22 to 25 ° C. Humidity is 45-60%.

[0010]

According to the present invention, when the entrance / exit door of the graft seedling curing device cannot be opened / closed and is confined in the refrigerator,
The emergency switch can be operated in the refrigerator, and the environment inside the refrigerator is automatically changed by the operation, which may lead to the risk of life (oxygen deficiency, high temperature,
High humidity) can be prevented.
