Description

[Detailed description of the invention] [Technical field of the invention] The invention relates to a refrigerator having a double door structure,
In particular, when opening one door, it prevents the other door from opening together due to friction between the gaskets, and also prevents the door body from being tilted to one side, which would impair the airtightness inside the refrigerator. It is related to the refrigerator that can be used.

[Technical background of the invention and its problems]

Generally, the door structure of a refrigerator is a deployable door, which consists of a periphery of the entrance on the housing side, which is formed into a substantially rectangular shape, and a magnetic gasket provided on the periphery of the surface of the door facing the inside of the refrigerator. It is configured to maintain airtightness inside the refrigerator through magnetic attraction.

However, in the case of a refrigerator having a double-door structure, one side of the door body on the free-opening end side has no engaging part on the housing side that engages with this side, and when the door is closed, it is located approximately in the center of the loading/unloading opening. It turns out. For this reason, the interior of the refrigerator is kept airtight by providing gaskets at the abutting portions of the left and right door bodies. Therefore, the engaging area of the magnetic gasket and the peripheral edge of the housing side entrance/exit becomes small, and the area around the opening center axis (hinge part) of the door body is reduced due to the action of magnetic force. Since the moment generated is small, there is a problem in that when one door is opened, the other door also opens due to the friction of the gaskets at the abutting portions.

In addition, as the magnetic force that attracts the door body to the housing weakens, the weight of the door body acts as a load on the hinge part, which increases the chance that the door body tends to sag, causing the door bodies to fall against each other. There was a problem that the fittings of the gaskets provided at the abutting portions were not aligned, making it impossible to maintain airtightness inside the refrigerator, and there was a demand for ensuring vertical sealing of the loading/unloading opening.

[Purpose of invention]

The present invention has been devised in view of the above-mentioned problems and to effectively solve them.

The purpose of this invention is to prevent, when opening one door of a refrigerator with a double door structure, the other door from opening together due to friction between the gaskets, and to prevent the door body from being tilted to one side. To provide a refrigerator that can prevent the airtightness inside the refrigerator from being impaired.

[Summary of the idea]

The present invention is a refrigerator that has a box-like housing with an opening on one side and a double-door door body that opens and closes by expanding the opening to the left and right. A gasket is provided which is raised and airtightly seals the inside and outside of the housing, and is fitted to the upper and lower edges of the opening of the housing into a gap formed inside the gasket when the door body is closed. The above object is achieved by providing a sealing member for sealing, and by providing an engaging portion on the door body and the peripheral edge of the opening of the housing to releasably attach to each other.

[Example of idea]

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a schematic configuration of a refrigerator according to the present invention. Reference numeral 1 denotes a housing, which is formed in the shape of a substantially rectangular parallelepiped box, and one side thereof is opened as an opening 2 for taking in and taking out stored items. This access port 2 is provided with door bodies 3 and 4 configured in a deployable double door structure that can be deployed to the left and right to open and close. As shown in FIG. 2, magnetic gaskets 6 are provided along the circumferential direction on the end surfaces of the upper, lower, left, and right side walls of the housing 1 that partition the peripheral edge 5 of the entrance/exit 2. 4 closes the door 2, the magnetic force causes the door body 3, 4 to close.
is adsorbed to keep the inside of the refrigerator airtight. Note that FIG. 2 shows a main part of a cross section taken along the - line when the door body 4 is closed in FIG. 1. In addition, a gasket 7 is provided at the abutting portions of the door bodies 3 and 4 on the free deployment end side to seal the entrance/exit port 2 when it is closed. It is formed by being raised. 8 is fitted so as to fill and seal a gap on the inside of the refrigerator which is formed between the gasket 7 and the end surface on the housing 1 side when the door bodies 3 and 4 close the access port 2. A side wall 9 that follows the outer shape of the inside of the refrigerator and forms the upper surface of the housing 1.
This is a seal member molded along the Therefore, the gap inside the refrigerator formed by the gaskets 7 of the closed doors 3 and 4 is sealed by the sealing member 8 in the opening and closing direction of the doors 3 and 4, and the sealing member 8 is also used to prevent loading and unloading. The vertical sealing performance of the opening 2 is ensured.

The upper part of the free unfolding end side of the surface facing the entrance/exit 2 side of each door body 3, 4 and the end face of the side wall 9 which engages therewith and forms the upper surface of the housing 1 are removably engaged with each other. Convex and concave engaging portions 10 and 11 that fit together and are fixed to each other are provided.

The convex engaging portion 10 provided on the door body 3, 4 side is
As shown in FIG. 3, there is a head 12 whose tip is formed with a smooth curved surface and a bulging outer surface, a door body 3,
4, and a neck portion 14 that connects these parts and is constricted.

Further, the concave engagement portion 11 provided on the housing 1 side is fitted into the side wall 9, and when the door bodies 3 and 4 close the access port 2, the head portion 11 of the convex engagement portion 10
A pleat section 15 is provided to sandwich the convex engaging section 10, and the opening at the tip of the pleat section 15 is narrowed to grip the neck section 14 of the convex engaging section 10.

Next, the operation of the present invention will be explained.

When the door bodies 3, 4 close the access port 2, the door bodies 3, 4 and the housing 1 are attracted to each other by the magnetic force of the magnetic gasket 6, and the convex engaging part 10 and the concave engaging part 11 are connected to each other. Since the door bodies 3 and 4 are fixed by fitting together, the door bodies 3 and 4 cannot be unfolded only by a force that resists the magnetic force. That is, unless the force is greater than the sum of the force for disengaging the convex engagement part 10 and the concave engagement part 11 and the force resisting the magnetic force, the door body 3,
4 cannot be unfolded to open the access port 2.

Therefore, when only one door body 3 or 4 is unfolded and opened, the frictional force between the gaskets 7 acts and the other door body 4 or 3 tries to open together, but this frictional force is Since the force is not greater than the sum of the force for separating the magnetic force and the force for resisting the magnetic force, the other door bodies 4 and 3 remain closed.

In addition, the weight of the door bodies 3 and 4 is supported almost equally by the suction engagement portion of the magnetic gasket 6, the concave and convex engagement portions 10 and 11, and the pivot support on the deployment center side. , 4 are not tilted to one side, therefore, the alignment of the packing 7 is maintained, and the airtightness inside the refrigerator is not impaired. Furthermore, since the loading/unloading port 2 is reliably sealed in the vertical direction by the sealing member 8, the airtightness inside the refrigerator is maintained.

The convex engaging portion and the concave engaging portion may be attached to either the door side or the housing side.

[Effect of idea]

As is clear from the above description, the present invention provides the following excellent effects.

(1) Airtightness inside the refrigerator can be maintained.

(2) When opening one door, it is possible to prevent the other door from opening together due to friction between the gaskets.

(3) The structure is simple and can be easily adopted.
