Description

  The present invention relates to an environment control device that controls an indoor environment such as a clean room or a sterile room, and a component member thereof.

  Conventionally, in a clean room, an aseptic room, etc., a so-called vertical laminar flow method, horizontal laminar flow method, or turbulent flow method is used to flow indoor air. The vertical laminar flow type sucks room air into the space inside the double floor and sends it to the space inside the double ceiling via a duct, and then removes dust etc. by the fan filter unit etc. in the ceiling. This is a system that recirculates indoors. The horizontal laminar flow type is a method in which the walls facing each other across the room are double walls, and air is stratified from one wall to the other. The turbulent flow type supplies air from the double ceiling. It is the system which performs suction from the side wall made into a double wall.

  On the other hand, in recent medical facilities, in order to perform treatment such as hematopoietic stem cell transplantation for leukemia patients and cell processing under aseptic conditions, there are increasing cases of renovating existing hospital rooms to clean rooms. However, in any of the above-described methods, it is necessary to make the floor, ceiling, and wall have a double structure, so the construction period and cost for renovation have been problems.

  Therefore, in recent years, as in Patent Document 1 and Patent Document 2, for example, a vertical laminar flow type clean room having a double floor structure using a so-called free access on an existing floor is used. The clean room disclosed in Patent Document 1 is configured such that the floor area of the clean room can be appropriately changed by free access and a movable wall surface (“partition” in Patent Document 1). Moreover, in Patent Document 2, a plurality of L-shaped return air ducts are arranged in a double floor formed by free access in order to eliminate bias in the cleanliness of indoor air.

JP 58-182046 A JP 2007-178065 A

  However, in Patent Document 1, since air in the underfloor space is sucked from below the partition wall that also serves as a duct, the distance from the partition wall differs depending on the position of the room, and the speed of sucking air from the floor varies. There is.

  On the other hand, in Patent Document 2, by arranging a plurality of return air ducts under the floor and devising the positions and orientations of the suction holes of the return air ducts, the air suction speed becomes uniform at any position on the floor. I have to. However, in the clean room of Patent Document 2, there is a problem that it takes time to install the return air duct under the floor, and when the indoor layout is changed, the position of the free access can be changed even if the position of the free access can be changed. Since the position cannot be easily changed, there is a problem that the range of change of the layout is limited.

  Also, in clean rooms using free access as in Patent Document 1 and Patent Document 2, when the underfloor is contaminated with chemicals, blood, etc., the space under the floor expands as a whole so that the chemicals and blood spread. And the problem that free-access support legs interfere with underfloor cleaning and disinfection.

  The present invention has been made in view of the above problems, and it is possible to easily install or change the air flow path according to the layout of the room or its change, and to clean the inside of the double wall or double floor. The purpose is to provide an environmental control device that can be easily sterilized.

The block type suction unit (hereinafter also simply referred to as “suction unit”) of the present invention, which has been made to solve the above problems, includes a suction unit that sucks air from the room, and an air supply that flows air from the suction unit A suction unit for use in the suction part of the environmental control device, which is formed in a hollow box shape, between a suction hole for sucking air from the room, and an adjacent suction unit or the air feeding part And a communication port for transmitting and receiving air, and is configured in a block shape that can be attached to and detached from the adjacent suction unit and / or the air supply section.
Here, the “contact port for sending and receiving air” includes both a contact port used for both sending and receiving air and a contact port used only for sending and receiving air.

  Thus, since the suction unit according to the present invention has a hollow box shape and has an adjacent suction unit and an air supply section and a communication port for sending and receiving air, connecting the indoor air sucked from the suction hole by connecting them. It can act as a duct that flows to the air supply section. Moreover, since it is configured in a detachable block shape, it can be easily assembled like a building block. Moreover, since the suction unit main body has a box shape, even if chemicals or blood spills inside, it can be prevented from spreading to other places. Furthermore, since the block suction unit is detachable, it can be removed and washed or sterilized when it becomes dirty with chemicals, blood, or the like, and can be replaced with a spare suction unit for washing.

  The block-type suction unit of the present invention preferably includes a lid and a suction unit main body having an opening closed by the lid, and the suction hole is provided in the lid. By doing so, the lid can be opened to clean the interior, and the lid can be replaced with a lid without a suction hole so that only the duct can function.

  An air supply unit according to the present invention is an air supply unit used in the air supply unit of an environmental control device including a suction unit that sucks air from a room and an air supply unit that flows air from the suction unit. An air inlet into which air flows in from the upstream side in the air flow direction, and an air outlet from which air flows out to the downstream side in the air flow direction, the suction part, and It is characterized by being configured in a detachable block shape with respect to adjacent devices among other air supply units. Thus, since the air supply unit of the present invention is configured in a detachable block shape, it can be easily provided on an existing wall or ceiling.

  The air supply unit of the present invention is an air supply unit used in the air supply unit of the environmental control device including an air supply unit that supplies air into the room and an air supply unit that flows air to the air supply unit. A communication port provided on the side wall of the room, having a hollow box shape, for sending and receiving air between an air supply hole for supplying air to the room and an adjacent air supply unit or the air supply unit. And is configured in a block shape that is detachable with respect to the adjacent air supply unit and / or the air supply unit. For example, in a horizontal laminar flow type clean room, the air supply section is provided on the side wall. However, on the side walls of hospital rooms and the like, oxygen, air, so-called OAVs with suction outlets often get in the way, and the case of adopting the turbulent flow method by abandoning the horizontal laminar flow method that provides high air cleanliness There are many. Thus, by making the wall surface installation type air supply unit a block type, it is possible to easily avoid an obstacle and install the air supply unit on the side wall.
