2. Description of the Related Art Electric warmers of the above type are known,
It is mainly used for storing towels and food.
This type of electric refrigerator is advantageous from various points such as energy saving if the air in the inner container can be heated as quickly as possible. In consideration of this point, it is desirable that the electric storage cabinet has a high sealing property between the door and the inner container. However, when the airtightness between the door and the inner container is enhanced, the air in the inner container expands as the internal temperature increases, and the internal pressure increases. Since this internal pressure acts in the direction of opening the door, there is a risk that the door will open on its own. Therefore, it is necessary to increase the door locking force to hold the door in the closed position, but if the door locking force is increased, the opening and closing operation lacks smoothness, and in particular, the electric warmer is used as a steamer. In many cases, the door is opened and closed more than 150 times a day, which may hinder use.

[0005] As described above, the electric refrigerator has a problem that the door is opened by the internal pressure when the sealing property between the door and the inner container is enhanced, and when the sealing property between the door and the inner container is poor, energy consumption is increased. There was a contradictory problem of bulk.

[0004] In a conventional electric refrigerator, the main body of the housing is made of sheet metal, and the door is provided with a rubber packing having a thickness of about 2 cm along the inner periphery of the door. Has a built-in magnet that locks the door with magnetic force. The rubber packing itself does not have a very good seal between the door and the inner container. In addition, in the conventional electric storage, the magnetic force is not absorbed on the hinge side of the door, and the sealing performance at that portion is deteriorated. As described above, the conventional electric refrigerator has a problem that the hermeticity between the door and the inner container is deteriorated to some extent and the amount of energy consumption increases, but there is no problem of opening the door.

[0005]

[Problems to be Solved by the Invention] However, in the conventional electric refrigerator, a structure for preventing the sealing between the door and the inner container from being enhanced is obtained from the structural point of view. Can not. Therefore, there is a danger that the hermeticity between the door and the inner container is unnecessarily deteriorated and unnecessary energy is consumed. In addition, it was unavoidable that the individual hermetic storages varied in hermeticity and fluctuated.

[0006] In view of the above-mentioned conventional problems, the present invention can set the sealing between the door and the inner container to a desired degree of sealing. Therefore, energy consumption can be achieved as long as the door is not opened by the internal pressure of the inner container. It is an object of the present invention to provide an electric refrigerator that can easily be set to be reduced.

[0007]

In order to achieve the above-mentioned object, the present invention provides an inner container provided in a main body of an electric warmer and forming a warmer room having an open front side, and an electric warmer. A door that opens and closes the opening of the inner container by rotating about an axis perpendicular to a surface on which the container is to be installed; A door packing capable of sealing the interior of the inner container with a high degree of sealing by being pressed against the front plate is provided, and a cutout portion is formed at a lower portion of the door packing. The present invention is effective when a drain receiver is arranged below the notch.

[0008]

According to the above construction, a door packing capable of sealing the inside of the container with a high degree of sealing is provided on the inner container side of the door, and a notch is formed in a part of the door packing. The degree of sealing between the door and the inner container can be set according to the width of the door, so that it is possible to easily set the degree of sealing with low energy consumption within the range where the door is not opened by internal pressure, and drain the drain from the notch can do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 are a perspective view and a cross-sectional view showing an embodiment of the electric refrigerator according to the present invention. In FIGS. 1 and 2, reference numeral 1 denotes a main body of a refrigerator of an electric refrigerator, and reference numeral 2 denotes an inner container that constitutes a refrigerator room provided in the main body of the refrigerator. The inner container 2 has an opening 3 formed on the front side, and the opening 3 is opened and closed by a door 4 rotatably attached to the main body 1 of the refrigerator. The door 4 is rotated about an axis substantially perpendicular to a surface on which the electric refrigerator is installed to open and close the opening 3 as shown in the figure.

[0010] Main body 1 and door 4 of the electric storage room
Is made of a synthetic resin, and the inner container 2 is formed by bending an aluminum plate or a cylindrical member 5 made of a heat-resistant resin molded product. 7 and a bottom plate 8 formed integrally with the bottom plate 7. And
The refrigerator main body 1 is assembled by sandwiching and supporting the tubular member 5 between the front plate 6 and the back plate 7, and has an excellent effect that the assembling work is simplified.
Since this configuration is not the gist of the present invention, detailed description will be omitted.

When the door 4 is closed, the electric storage is provided with a lock means for holding the door at the closed position. As the lock means in this embodiment, as shown in FIGS. 4 and a stop member 13 provided on the refrigerator main body 1 to which the hook member 9 is locked.
It is composed of The hook member 9 is mounted so as to be rotatable about a shaft 10, and has a step portion 1 of a stopper member 13 at one end.
A hook 9 is formed on the hook 4 and a spring 12 is anchored at the other end. The hook member 9 is urged to rotate counterclockwise about the shaft 10 by the spring 12, but the lower end of the opening 11 of the door 4 functions as a stopper, and the hook member 9 is generally substantially horizontal. Held in position. 1 and 2, reference numeral 18 denotes a heater assembly, 19 denotes a control board,
