Description

  Embodiments of the present invention relate to an air conditioner including, for example, a ceiling-suspended indoor unit.

  In an air conditioner provided with an indoor unit and an outdoor unit, the indoor unit is attached in a state in which the indoor unit is in close contact with the ceiling plate. For this reason, unlike a so-called wall-mounted indoor unit, the indoor unit does not protrude from the wall surface of the room and does not cause a feeling of pressure in the room.

  This type of air conditioner needs to reduce the dimension in the height direction of the unit main body (housing) of the indoor unit as much as possible, but has few dimensional constraints in the width direction of the unit main body. Therefore, the unit main body is formed wide in the width direction, and the air blower blows out the air heat-exchanged with the heat exchanger from a wide range along the ceiling surface, thereby improving the heat exchange efficiency.

  A first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a perspective view showing an appearance of an indoor unit constituting the air conditioner, and FIG. 2 is a longitudinal sectional view of the indoor unit.

  FIG. 1 shows a unit main body 1 as an air conditioner main body. The unit body 1 is hooked on a plurality of suspension bolts suspended from a beam or the like on the back of the ceiling (not shown). The unit body 1 is exposed indoors in a state of being very close to the ceiling surface. The unit body 1 is formed so that the dimension in the width direction is extremely larger than the dimension in the thickness direction. The thickness direction of the unit body 1 can be rephrased as the height direction. Similarly, the width direction of the unit body 1 can be rephrased as a horizontal direction.

  The unit body 1 includes a bottom plate portion 1a constituting the lower surface, a top plate portion 1b constituting the upper surface close to the ceiling, a pair of left and right side plate portions 1c connecting the bottom plate portion 1a and the top plate portion 1b, and a back surface portion. 1d.

  A suction port 2 is provided in the bottom plate portion 1a. The suction port 2 extends over the entire length along the width direction of the bottom plate portion 1a and has a size of about half of the bottom plate portion 1a in the front-rear direction. A grill 10 and a filter 11 are detachably fitted in the suction port 2 along the width direction of the bottom plate portion 1a.

  An outlet 3 is provided on the front surface of the unit body 1. A horizontal louver 12 is attached to the outlet 3 so as to be openable and closable. Further, a plurality of vertical louvers (not shown) are rotatably attached behind the horizontal louver 12 of the outlet 3.

  As shown in FIGS. 2 to 4, a partition plate 6 is provided inside the unit body 1. The partition plate 6 is erected along one side edge of the suction port 2 in which the grill 10 is fitted, and extends so as to contact the top plate portion 1 b of the unit body 1. In addition, the partition plate 6 extends so as to contact the left and right side plate portions 1 c of the unit body 1. For this reason, the partition plate 6 divides the inside of the unit main body 1 into two chambers, a blower chamber A and a heat exchange chamber B.

  That is, the blower chamber A and the heat exchange chamber B are arranged in parallel inside the unit body 1 with the partition plate 6 interposed therebetween. The blower chamber A has a suction port 2, and the blower S and the electric component box 9 are arranged in the blower chamber A. The heat exchange chamber B has an outlet 3, and an indoor heat exchanger 5 and a drain receiver 7 are disposed in the heat exchange chamber B.

  The electrical component box 9 disposed in the blower chamber A accommodates electrical components that control driving of the blower S and the like. The electrical component box 9 is fixed to the unit main body 1 so as to be positioned in a narrow space formed between the blower S and the back portion 1d of the unit main body 1.

  The indoor heat exchanger 5 is disposed in the heat exchange chamber B in a posture that is strongly inclined forward because the dimension along the height direction of the unit body 1 is limited. The drain receiver 7 is installed below the indoor heat exchanger 5. The drain receiver 7 is made of, for example, a thick synthetic resin material, and has an area that occupies substantially the entire region of the bottom surface of the heat exchange chamber B. Therefore, the drain receiver 7 receives all of the drain water droplets generated along with the refrigeration cycle operation dripping from the inclined indoor heat exchanger 5.

  As shown in FIG. 2, an upper heat insulating material 30 that supports the upper end portion of the indoor heat exchanger 5 is provided in the upper part of the heat exchange chamber B. The upper heat insulating material 30 is formed to be thick like the drain receiver 7 so that heat (warm / cold heat) accompanying the refrigeration cycle action of the indoor heat exchanger 5 is not transmitted to the plate material forming the unit body 1. .

  Next, the configuration / action of the blower S and the mounting structure of the blower S with respect to the unit body 1 will be described.

  FIG. 3 is a bottom view of a part of the unit body 1 for explaining the mounting structure of the blower S according to the first embodiment, and FIG. 4 is a perspective view of the blower S according to the first embodiment as viewed from above. FIG.

  The blower S provided in the unit main body 1 uses a double-axis fan motor 15 in order to blow heat exchange air over a wide range along the width direction of the unit main body 1.

The fan case 17 is provided with a suction opening around the rotation axis a and integrally includes a nozzle portion 17 a that penetrates the partition plate 6 and protrudes into the heat exchange chamber B.

  When the fan 16 rotates, indoor air is sucked into the air blowing chamber A of the unit body 1 from the suction port 2 through the grill 10 and the filter 11. The air sucked into the blower chamber A is sucked into the opening of the fan case 17 and blown out from the nozzle portion 17a to the heat exchange chamber B. That is, the fan case 17 guides the air blown from the fan 16 to the nozzle portion 17a.

  The indoor heat exchanger 5 disposed in the heat exchange chamber B changes the air into cold or warm heat exchange air by heat exchange with the air blown from the nozzle portion 17a. The heat exchange air is guided to the vertical louver and the horizontal louver 12 and blows out into the room from the blowout port 3. Thereby, indoor cooling or heating is performed.
