Description

  The present invention relates to a refrigerator that cools stored food and the like.

  In order to cool and store a large amount of food, etc., for example, a direct cooling type chest freezer is used. The chest type freezer includes an opening on the upper surface, a cooling chamber that cools an accommodated object, and an open / close door that is connected to the upper edge of the cooling chamber via a hinge and opens and closes the opening. A seal member that seals between the open / close door and the cooling chamber is provided at the peripheral edge of the open / close door.

  The cooling chamber is provided with a refrigeration machine including an evaporator and a compressor, and a pipe for removing frost attached to the evaporator. The cooling chamber and the outside communicate with each other by a pipe. When the power is on, the pipe is closed because defrosting is not performed. The defrosting is performed manually. For example, the power of the chest type freezer is turned off, the pipe is opened, the frost is melted, and the defrosting water is discharged from the pipe.

  When the opening / closing door is opened while the chest type freezer is driven, air having a temperature higher than the room temperature of the cooling chamber flows into the cooling chamber. The open / close door is closed, and the air that flows in is cooled and contracts. Therefore, the air pressure in the cooling chamber becomes negative with respect to the external pressure, and the burden on the user when opening the door is increased.

  In order to prevent the atmospheric pressure in the cooling chamber from becoming a negative pressure, it has been conventionally proposed to form an air passage between the seal member and the open / close door (see, for example, Patent Document 1). In patent document 1, the groove | channel which inserts a sealing member in the opening / closing door is formed, and the sealing member is inserted in this groove | channel. The ventilation path is formed by making the dimension of the portion of the seal member inserted into the groove smaller than the dimension of the groove.

  The open / close door includes a door plate positioned on the upper side, and a door liner facing the door plate and positioned on the lower side. A urethane foam material is filled between the door liner and the door plate. When filling the urethane foam material, the door liner and the door plate are pressed with a jig in order to prevent leakage of the filled urethane foam material.

  Since the peripheral part of a door liner and a door plate contacts, each peripheral part is pressed down with a jig. In order to apply sufficient pressure to each peripheral edge from the jig, the peripheral edge of the door liner is formed flat. In addition, the groove | channel is formed inside the peripheral part.

JP-A-8-82472

  In order to secure the air passage, it is necessary to secure a gap not only in the groove but also in a flat portion, but it is difficult to secure a gap in the flat portion. Even if a gap is ensured in the flat part, the displacement of the hinge or the dimensional change due to deterioration of the seal member may occur over time, and as a result, the distance between the open / close door and the cooling chamber becomes closer, and the seal member May be crushed and the gap may be filled.

  When the pressure in the cooling chamber is negative, the seal member is crushed, the gap is filled, and the air passage may be blocked.

  The present invention has been made in view of such circumstances, and even if there is a flat portion at the peripheral edge of the open / close door or when the seal member is crushed, an air passage that communicates the cooling chamber and the outside is provided. It aims at providing the refrigerator which can be ensured.

  The refrigerator according to the present invention has an opening, a cooling chamber that accommodates and cools an object, an opening / closing door that is connected to an edge portion of the opening via a hinge, and opens and closes the opening, and the opening / closing In a refrigerator having a seal member provided at a portion of the door facing the cooling chamber, a protruding portion protruding toward the seal member is provided at the facing portion.

  The refrigerator according to the present invention includes a plurality of the protrusions, and the plurality of protrusions are arranged in parallel along the edge portion of the opening / closing door at a predetermined interval.

  The refrigerator according to the present invention is characterized in that the projecting portion is located at any one of the opposing portions.

  In the refrigerator which concerns on this invention, a protrusion part is provided in the opposing part of an opening-and-closing door, and a clearance gap is ensured between this sealing member and an opposing part by this protrusion part. Even when the facing portion is flat or the seal member is crushed, the clearance is secured by the protruding portion, the air passage is secured, and the burden on the user when opening the open / close door can be reduced. it can.
