Description

The present invention relates to a vault.

Conventionally, there is a storage described in Patent Document 1 below. The storage described in Patent Document 1 includes an electrode arranged inside the storage and a power source for applying a voltage to the electrode. The vault is formed in the shape of a rectangular box. The electrodes are fixed to the inner surface of the bottom wall portion or the inner surface of the upper wall portion of the storage, and form an atmosphere of an electrostatic field inside the storage based on the voltage applied from the power source. As a result, it is possible to maintain the freshness of the fresh food or the like stored in the storage for a long time as compared with the case where an electrostatic field is not formed in the storage.

Since the electrodes have a relatively large weight, when a plurality of electrodes are to be fixed to the inner surface of the upper wall portion of the storage, a reinforcing material is often provided on the inner surface of the upper wall portion of the storage. For example, at the time of manufacturing the storage, a special process for fixing the reinforcing material is applied to the inner surface of the upper wall portion, and then a plurality of electrodes are installed so as to be suspended from the reinforcing material. As described above, when the electrodes are to be arranged in the storage, complicated processing is required for the storage. This is a factor that hinders the spread of storages in which electrodes are installed, and improvement thereof is desired.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a storage in which an electric field forming member can be more easily arranged.

The storage that solves the above problems includes a storage main body having a storage chamber inside, and an electric field forming member that forms an electric field inside the storage chamber. A mounting portion on which an electric field forming member is placed is provided on the side wall portion of the storage body.
According to this configuration, the arrangement of the electric field forming member in the accommodation chamber is completed only by placing the electric field forming member in the mounting portion provided in the accommodation main body. Therefore, since it is not necessary to perform complicated processing on the storage chamber main body in order to arrange the electric field forming member in the accommodation chamber, the electric field forming member can be arranged more easily.

In the above-mentioned storage, it is preferable that a plurality of electric field forming members are placed on the mounting portion.
According to this configuration, it is possible to form a wider electric field by combining a plurality of electric field forming members. Further, since it is possible to reduce the size of each electric field forming member, it becomes easy to install the electric field forming member in the storage.

In the above-mentioned storage, when the two side wall portions arranged opposite to each other in the storage storage main body are the first side wall portion and the second side wall portion, they are provided on the first side wall portion as a mounting portion to form an electric field. It is preferable to include a first mounting portion on which one end of the member is mounted, and a second mounting portion provided on the second side wall portion on which the other end of the electric field forming member is mounted.

According to this configuration, both ends of the electric field forming member can be supported by the first mounting portion and the second mounting portion, respectively, so that the electric field forming member can be installed in a more stable posture.
In the above-mentioned storage, the electric field forming member includes an insulating member having an electrically insulating property and an electrode member fixed to the outer surface of the insulating member and forming an electric field based on the application of a voltage. Of the electrode member and the insulating member, only the insulating member is preferably placed on the placing portion and the second mounting portion.

According to this configuration, the electrode member can be installed in the mounting portion.
In the above-mentioned storage, when the direction in which the first side wall portion and the second side wall portion face each other is a predetermined direction, the insulating member has a shape longer than the electrode member in the predetermined direction, and is the first. It is preferable that both ends of the insulating member in a predetermined direction are mounted on the mounting portion and the second mounting portion, respectively.

According to this configuration, it is possible to easily realize a structure in which only the insulating member among the electrode member and the insulating member is mounted on the first mounting portion and the second mounting portion.
In the above storage, it is preferable that the insulating member is entirely made of an insulating material. Alternatively, the insulating member is preferably formed by applying an insulating material around a predetermined material.

In the above-mentioned storage, the first mounting portion is a member having an L-shaped cross section having a portion fixed to the first side wall portion and a portion on which one end of the electric field forming member is placed. The placement portion is preferably a member having an L-shaped cross section having a portion fixed to the second side wall portion and a portion on which the other end portion of the electric field forming member is placed.

According to this configuration, it is possible to easily realize a mounting portion on which an electric field forming member can be mounted.
In the above-mentioned storage, the mounting portion is preferably formed of an insulating material having an electrically insulating property.

According to this configuration, it becomes difficult to form an electric field from the electric field forming member toward the mounting portion. As a result, a more uniform electric field can be formed inside the storage.
The above storage is preferably new or used.

According to the storage of the present invention, the electric field forming member can be arranged more easily.
