摘要

The automatic opening and closing device for open type refrigeration showcase starts. Automatic opening and closing device for the open-type refrigeration showcase disclosed is capable of opening and closing the front of the cold storage showcase refrigeration unit to perform the cold storage of the display object to be display on the front opening and closing the door member; Motion sensing member capable of detecting the human body of the cold storage showcase body front; The refrigeration door opening and closing member driving member is driven to be opened or closed to the front of the refrigerated showcase body; And if the human body detection in the front body by means of the cold storage showcase sensing member detected, a door member opening and closing the cold storage and transfer the open command to open the front of the cold storage showcase body, the cold storage by the PIR sensing member Showcase case, not a human body detected on the front, a door member opening and closing the cold storage control member to pass close command to close the front of the cold storage showcase body; includes, The PIR sensing member senses the time to stay in the human body forward the cold storage showcase body, the control member is not less than the reference time as the body is set in advance the time staying in the cold storage showcase front body is detected by the PIR sensing member If it is determined characterized in that for transmitting the open command to the drive member. According to the automatic opening and closing device for the open-type refrigeration showcase is started, an open-type refrigeration showcase are refrigerated for an automatic opening and closing device opening and closing the door member, PIR sensing member, as a driving member and a control member, towards the front of the cold storage showcase body buyers When such a maintenance and access to the front of the open state of the cold storage showcase main body to be only the front opening of the cold storage showcase body, if you do not need to be over the opening of the cold storage showcase, etc. do not have access to the buyer's body, such as the it can maintain a closed state by the front door open and close members of the refrigerated showcase refrigerated body, yet able to maintain the accessibility of such buyers have the advantage of being able to reduce the energy required for refrigeration. ;
