Description

  The present invention relates to a simultaneous supply / exhaust type range hood that simultaneously supplies exhaust gas such as exhaust gas generated during cooking and outdoor fresh air.

  In recent years, due to energy saving and soundproofing due to changes in the living environment, high-rise houses such as condominiums and single-family houses are becoming airtight and highly insulated. In the case of an old house, there were many gaps and negative pressure when using a range hood could be avoided, but in terms of heat insulation and sound insulation. In addition, when a range hood was used in a highly airtight and highly insulated house, it caused traps such as abnormal noise due to poor suction, and poor physical condition due to lack of fresh air.

  As a range hood for a house with high airtightness and high heat insulation as described above, a simultaneous supply / discharge type range hood equipped with an air supply unit for taking in outside air corresponding to the house has come to be frequently used. In addition, the design of the range hood has also changed, and the hood, which is the exhaust gas collection space, is not a deep, generally box-shaped type, but a thin, generally box-shaped flat with an opening on the bottom. The appearance structure of the range hood is often used in a form in which a substantially box-shaped blower box containing an exhaust device is arranged at the approximate center position of the thin box-shaped hood top plate.

  The range hood installation environment shown above is arranged above the cooking utensil, in the middle of the hanging cabinet provided near the ceiling, and for the exhaust and air supply unit of the blower box arranged on the top of the range hood A curtain plate is attached to blind the connected air supply duct. The curtain is not only blindfolded, but also has an outlet for fresh air taken from the outside on the front side of the curtain. The hanging cupboard through the duct is hollow.

  The space where the exhaust and air supply duct connection work and the members such as each connection unit are arranged is the hood top plate and the ceiling on the opposite side, the wall surface on the opposite side of the curtain plate, and the suspension in the horizontal direction when the range hood is viewed from the front It is performed in the part surrounded by the side wall of the cupboard. The space used for the duct connection work varies depending on the size of the range hood to be installed.The dimensions are limited to three types in the longitudinal direction of the hood portion when viewed from the front, and the depth is limited to one type according to the size of the hanging cabinet. It has become almost standardized within the range hood industry. That is, the size of the space that can be used for duct connection work or the like differs depending on the size of the range hood to be used, and the working space becomes narrower as the size decreases.

A joint is used to connect the range hood side to the duct. FIG. 8 shows a joint used for duct connection. FIG. 8A shows a normal type without a shutter, and FIG. 8B shows an electric hermetic shutter which is a duct joint that is electrically driven by a shutter B2. The type (b) indicates a type in which the shutter B2 is opened and closed in conjunction with the exhaust device by a gear B4 in which the shutter B2 is mounted on the axis of the shutter drive shaft B3 and a transmission gear B5 that transmits the driving force of the motor M. With this arrangement, the total length of the joint is about twice that of the normal type (a) without a shutter. Note that the dimension L in the figure indicates the total length of the normal type (a) for comparison with the length. In addition, since the electric closed shutter is closed when not in use, it is useful for energy saving by soundproofing and preventing outside air from entering the room, and is always equipped with a simultaneous supply / discharge range hood. .

  Duct connection work is performed after the range hood is attached. Depending on the construction site, the duct exists in a state of protruding from the ceiling side or side, or from the rear side of the range hood, and the position of the air supply box is adjusted to connect the duct.

The air supply box used for connection with the conventional air supply duct is substantially box-shaped, has air supply openings on the front, and has openings for connecting ducts on the top, both sides, and the back. By using a dedicated attachment, the opening except for the duct connection portion is closed simultaneously with the duct connection.
Duct connection work is done by placing an air supply box on the top of the hood and sliding it from the front so that the end of the duct fits in the opening of the air supply box. The attachment which consists of is inserted and the connection operation | work with a duct is performed from the inside of an air supply box (for example, refer patent document 1).

  When a fitting, especially a long electric sealed shutter is attached to the above-mentioned air supply box, the space used for the attachment is sufficient in the upper part, but the size of the hood part is smaller when attaching to the side wall and the rear side. If the air supply box is small or the mounting position of the air supply box is too close, the distance between the air supply box and the wall where the duct is located is very close. I can't. In addition, when an electric hermetic shutter is attached, the tip of the electric hermetic shutter is outside the dimensions of the hood, and the connection work is not performed on the hanging cupboard, although the adjacent hanging cabinet is hollow. It becomes a form to be performed in the inside, and the work is hindered.

Japanese Patent Laid-Open No. 11-173617

  The problem to be solved by the present invention relates to the connection between a range hood provided with a blower box containing an exhaust device on the top of the hood and the supply duct, and the connection between the supply duct and the range hood in a limited space In addition to increasing the degree of freedom in installation direction and workability during work, the connection to the duct can be connected to the duct even if the joint used to connect the duct and the range hood uses a long electric closed shutter. It is to provide a simultaneous supply / discharge type range hood which can be performed within the dimensions.

In order to solve the above-mentioned problems, the present invention is arranged on a hood top plate in a range hood with a blower box incorporating an exhaust device connected to an exhaust duct and an air supply box connected to an air supply duct communicating with outside air. In the simultaneous supply / exhaust type range hood, the air supply box includes a plurality of attachment openings used for connection of an air supply duct configured to be openable and closable by a plate-like member, and the air supply box includes the air supply box. is arranged capable of changing to the right or left side of the air blowing box in the front view, the plurality of mounting openings, mounting the joint duct via a connecting member to the opening for the desired attachment, said attachment Since approximately half of the total length of the duct joint is in the air supply box, the air supply box, which is the passage of the air taken in, is connected to the air supply duct. Can be arranged according to the direction (claim 1).

The air supply box has an opening formed in the shape of a discharge port as an air communication portion on the front surface side (screen plate side) of the air supply box, and can be opened and closed by a plate-like member on the other surfaces except the front surface and the bottom surface portion. provided configured duct fitting disposition opening portion on each side, front with openings and a separate member which can be removed (claim 2).

A connection member in the form of a bowl is used to connect the joint used for connecting the air supply box and duct, and an opening is provided on the opposite side of the opening. The flange portion formed in this manner is provided in the periphery, and the coupling and the connecting member are integrated by the flange portion (claim 3 ).

According to the present invention, in order to facilitate the duct connection work in the limited space on the upper surface of the hood part, the separate air supply box is arranged near the duct opening part to perform the connection work with the duct. The piping can be connected without complicated ways. Since piping is not performed in a complicated route, the connection work between the duct and the joint is very easy and does not place a burden on the worker.
In addition, when using an electric closed shutter with a long overall length, it is configured so that approximately half of the total length is housed in the air supply box and the length that protrudes from the air supply box is shortened. When installing the range hood, especially when the range hood is installed, the connection work with the duct can be reliably performed within the dimensions of the range hood even when working on the left and right sides of the front view and the back side.

  Since there are openings for installing duct joints on each side except the front and bottom surfaces of the air supply box, after installing the air supply box at a position that matches the duct at the construction site, the joints can be arranged along the duct. I can do it. The front part provided with the opening is configured to be removable. The front part can be removed during construction, and the inside of the air supply box can also be used as a duct connection work space.

  The connecting member has a substantially bowl shape with a continuous opening, and is integrated with the base of the electric hermetic shutter and the inward flange of the connecting member with screws, etc., and the connecting member with the joint removed is removed from the front part After inserting from the inside of the air supply box and attaching to the duct, the connection member is fixed to the air supply box from the inside. Since most of the total length of the electric hermetic shutter is housed in the air supply box, the connection work with the duct can be performed within the range of the range hood.

  The range hood is composed of a blower box containing an exhaust device on the top of the hood and a separate air supply box disposed near the blower box.

  In addition, the air supply box has a connection opening used for connecting to the curtain on the front surface, and mounting openings on each surface except for the front and bottom surfaces, and connected to the mounting opening used for the duct connection. Members are used, and plate-like members are used for the other openings.

An embodiment of the range hood of the present invention will be described with reference to FIG.
The range hood A is arranged above the cooking utensil (not shown), in the middle of the hanging cabinet E located near the ceiling F, and the duct and the range hood are connected to the back of the curtain plate D with the outside air outlet D1 on the front. In space G on the side. In the space G, an air supply box 2 containing an exhaust device 22 disposed at a substantially central position of the hood top plate portion 13 and an air supply box 3 in the vicinity of the air supply box 2, that is, on the right side in FIG.

The distance is only the dimension L which is almost the same length as the normal type (b). When using a simultaneous supply / exhaust type range hood, an electric hermetic shutter that is twice as long as the normal type is an equipment that must be used. It is not possible to directly attach an electric sealed shutter-type joint having a long overall length to the surface 314 of No. 3.

  In order to attach the above-described long electric hermetic shutter, the present invention has a structure in which approximately half the entire length of the electric hermetic shutter is accommodated in the air supply box. As a result, there is a long portion in the air supply box as compared with the normal type without the shutter, so that the portion of the dimension L in the figure has a tip portion of the electric hermetic shutter. Is the same as the form in which the normal type joint is directly attached to the air supply box. After the combined work of the duct and the joint, the work of integrating the aluminum tape around the overlapped portion of the installed duct and the joint and integrating them can be performed in the portion of the dimension L within the range hood size range.
