  • Patent number: 8931292
    Abstract: A refrigerated showcase is provided that can easily carry out a maintenance operation and the like of a cooling mechanism disposed in a machine chamber. A machine chamber 13 is defined on a side of a heat insulating box 16 defining a storage chamber 12 and also provided with a cooler to cool the storage chamber 12 to have a cooling mechanism 80 disposed therein to circularly supply a refrigerant to the cooler, and a front side of the storage chamber 12 and the machine chamber 13 is covered with a single front glass 14. Then, a side of the machine chamber 13 is defined by a detachable second side panel to configure the machine chamber 13 to open laterally in a state of removing the second side panel, and also the cooling mechanism 80 is placed on a unit base 38 drawable from the machine chamber 13 to configure to allow the unit base 38 to be drawn from the machine chamber 13 via a side opening of the machine chamber 13 opened by removing the second side panel.

  • Patent number: 8033129
    Abstract: A showcase where an illumination device is placed outside a receiving chamber to enable effective use of the space in the receiving chamber. The inside of an insulated box body (16) having front glass (18) fitted in a front opening (56) is defined to form a receiving chamber (52). An upper evaporator (34) is placed in an upper insulating layer (54) of the insulated box body (16) so as to be in contact with a cooling plate (62) defining the upper surface of the receiving chamber (52). An opening (64) is formed in that portion of the cooling plate (62) with which the upper evaporator (34) is not in contact, and a receiving space (66) is formed in that portion of the upper insulating layer (54) to which the opening (64) faces. A holder (78) is placed at the receiving space (66), and inside the holder (78) is received and fixed an LED illumination device (70). The opening (64) is closed by a cover (86) with packing (84) in between, and the inside of the holder (78) is maintained in a sealed state.

  • Publication number: 20080047286
    Abstract: The temperature of an accommodating room is adjusted without causing drop of melting water from an upper evaporator onto the accommodated food materials. A cold storage showcase includes a cooling circuit 50 in which an upper evaporator 40 provided on an upper side of an accommodating room 14 and a lower evaporator 42 provided on a lower side of the accommodating room 14 are connected to a cooling apparatus. The upper evaporator 40 and the lower evaporator 42 are connected in parallel with the cooling apparatus. An electromagnetic valve SV for supplying or interrupting circulation of a cooling medium in the lower evaporator 42 is provided halfway a second route R2 on an upstream side of the lower evaporator 42. During a cooling operation, the accommodating room 14 is cooled at all times by the upper evaporator 40. When temperature detecting means Th detects a drop in temperature of the accommodating room 14, the electromagnetic valve SV is closed to stop the cooling by the lower evaporator 42.

  • Patent number: 5189706
    Abstract: An acoustic apparatus comprises an inner cabinet, a vibrator mounted thereon and an outer cabinet. The inner cabinet and the outer cabinet constitute an acoustic cabinet having a closed cavity. The outer cabinet covers the inner cabinet with a predetermined gap formed between the inner peripheral surface of the outer cabinet and the outer peripheral surface of the inner cabinet and has an opening causing the gap to communicate with the external region of the acoustic cabinet and to function as a resonance port. The resonance port and the closed cavity constitute a resonator. The vibrator is provided so as to face the closed cavity. The resonator radiates a resonant sound from the open end of the gap, i.e., the resonance port, upon being driven by the vibrator.
