Definitions

  • the present invention relates to a ceiling-mounted air conditioner of which unit body is mounted in a ceiling.
  • a control box and other components are detachably attached to an outer side surface of the unit body, and a blower unit including a blower fan, a motor and other components is detachably/attachably mounted in the unit body so as to take out the whole blower unit from the unit body.
  • PTL1 discloses a blower unit detachably/attachably mounted in a unit body in that the unit body is provided with a pair of support rails on an upper panel of the unit body, and an impeller and a motor of a blower unit are integrally inserted slidingly along the support rails into the unit body from an inspection port formed in a side panel, so that the impeller is mounted in a fan case fixed to a rear panel of the unit body.
  • PTL2 discloses an approach for facilitating a maintenance operation of an air conditioner, in which a pair of support fittings on which a fan motor base is mounted is attached to a pair of frames oppositely mounted on a base of a body, and the fan motor base equipped with a fan motor is inserted and mounted from above onto the pair of support fittings, and then is slidingly moved to a predetermined setting position to be fixed there, thus the fan motor can be detachably/attachably mounted.
  • the fan casing is fixed to the unit body, and only the impeller and the motor of the blower unit can be slidingly inserted and mounted into the unit body through the support rails.
  • this may cause no inconvenience in attaching and detaching the blower unit in a maintenance operation.
  • the above mentioned configuration however cannot be applied to an air conditioner using a dual-axis motor and a blower unit equipped with impellers on opposite ends of its motor shaft or an air conditioner using plural blower units.
  • PTL2 discloses the configuration in which the fan motor base integrated with the fan motor is inserted and mounted from above onto the pair of support fittings. Thus, predetermined space is required above the support fittings, which increases the unit body size, and this configuration cannot be applied to a ceiling-mounted air conditioner using a blower unit directly mounted to a top plate of a unit body.
  • the present invention has been made in the light of the above facts, and has an object to provide a ceiling-mounted air conditioner that facilitates attachment and detachment of a blower unit to a unit body regardless of the number of blower units, as well as realizes improvement of deformation and vibration characteristics of the top plate of the unit body.
  • the present invention provides a ceiling-mounted air conditioner including a unit body in a box shape mounted in a ceiling, and a heat exchanger and a blower unit that are mounted in the unit body, wherein the unit body includes: a support member bent substantially at a right angle, one surface of which is configured to be a partition plate for partitioning an inside of the unit body into an inlet region and an outlet region, and the other surface of which is configured to be a support plate for supporting at least one fan and at least one motor of the blower unit, and the blower unit is integrated with the support member.
  • the unit body further includes: a pair of rail members installed in parallel at a predetermined distance therebetween on an inner surface of a top plate from one end to the other end of the top plate of the unit body; and an aperture provided in one side surface of the unit body, and the blower unit is slidingly inserted between the rail members from the aperture so as to be mounted into the unit body through the support member.
  • the unit body includes: a support member bent substantially at a right angle, one surface of which is configured to be a partition plate for partitioning an inside of the unit body into an inlet region and an outlet region, and the other surface of which is configured to be a support plate for supporting at least one fan and at least one motor of the blower unit, and the blower unit is integrated with the support member.
  • the unit body further includes: a pair of rail members installed in parallel at a predetermined distance therebetween on an inner surface of a top plate from one end to the other end of the top plate of the unit body; and an aperture provided in one side surface of the unit body, and the blower unit is slidingly inserted between the rail members from the aperture so as to be mounted into the unit body through the support member.
  • the blower unit is drawn to one side of the unit body together with the support member from the aperture provided on the one side surface of the unit body along the pair of the rail members, and the blower subunit integrated with the support member is taken out to the outside, so as to carry out the inspection and maintenance operation thereof.
  • the above described configuration facilitates a maintenance operation applied on the blower unit taken out from the unit body mounted in the ceiling, and enhances efficiency of the operation.
  • the pair of the rail members can also serve as the reinforcement member for the top plate of the unit body, thereby providing a required level of improvement in deformation and vibration characteristics of the top plate where the blower unit is mounted without increasing the thickness of the top plate.
  • the blower unit may have an outlet port of the fan projecting into the outlet region through the partition plate of the support member.
  • the configuration of the outlet port of the fan included in the blower unit projecting through the partition plate of the support member into the outlet region can directly introduce the outlet air blowing from the outlet port of the fan into the outlet region in the unit body, which is partitioned by the partition plate.
  • the rail members may be formed of a plate member whose cross section is bent in a crank shape and whose rail portions are oppositely fixed to an inner surface of the top plate of the unit body.
  • the rail members are formed of a plate member whose cross section is bent in a crank shape and whose rail portions are oppositely fixed to an inner surface of the top plate of the unit body.
  • Configuring one side of the plate member having the cross section bent into a crank shape to be the attachment portion to the top plates, and configuring the other side thereof to be the rail portions oppositely mounted to the inner surface of the top plate of the unit body enable the plate member in the crank shape to serve as the pair of the rail members allowing the blower unit to be slidingly inserted and mounted into the unit body as well as the reinforce member for the top plate. Accordingly, using the rail members for installing the blower unit as the reinforcement member for the top plate improves deformation and vibration characteristics of the top plate of the unit body at a required level, thereby simplifying the structure of the unit body and reducing the cost.
  • a cover may be detachably attached to the aperture, and may serve as an attachment seat for a control box.
  • the cover is detachably attached to the aperture of the unit body, and is also used as the attachment seat for the control box. Accordingly, when the blower unit in the unit body is maintained, the cover together with the control box is detached so that the blower unit can be taken out from the aperture for the maintenance.
  • the cover is also used as the attachment seat for the control box, and the control box can be mounted onto the outer side surface of the unit body. Without complicating the attachment and detachment operation at the time of maintenance, the cover can also be used as the attachment seat for the control box, thereby simplifying the structure of the unit body and reducing the cost.

  • the cover 27 along with the control box 15 is detached from the unit body 2 so as to open the aperture 26.
  • the blower unit 11 can be taken out to one side of the unit body 2. Since the blower unit 11 is divided into plural individual blower subunits (blower subunits 11A, 11B), the frontmost blower subunit 11A together with the support member 20A is drawn to one side of the unit body 2 along the pair of the rail members 24, 25, as illustrated in Figure 3(B) , so as to take out the blower subunit 11A from the unit body 2.
