As shown in fig. 4 and 5, a front surface suction port 30 for taking indoor air into the interior is formed in the front surface of the front surface case 3. As shown in fig. 5, an upper surface suction port 31 for taking indoor air into the interior is formed in the upper surface of the front surface case 3. The front surface suction port 30 and the upper surface suction port 31 are covered with a common filter 12 that collects dust in the air-conditioned space. As shown in fig. 1 to 4, an air outlet 32 extending in the left-right direction is formed in a lower portion of the front surface case 3. The air outlet 32 is provided with an airflow direction adjustment plate 13 that adjusts the vertical airflow direction of the blown air.
Inclined surfaces 5 are formed on the left and right side edges of the front surface case 3, and the inclined surfaces 5 face the side edges of the front surface panel 4 and are inclined inward. Since the indoor unit 100 includes the inclined surface portion 5, a sense of depth can be given when viewed from the front surface side, and a high-level impression can be given to the user.
The front surface panel 4 covers a front surface suction port 30 formed in the front surface of the front surface case 3. The front panel 4 is rotatably attached to the front surface side of the front housing 3 via a rotation mechanism 6. The front surface panel 4 can be rotated from a position shown in fig. 1, in which the front surface of the front surface case 3 is closed, to a position shown in fig. 4, in which the front surface of the front surface case 3 is opened. As shown in fig. 5, the turning mechanism portion 6 includes: a rotating shaft 60 provided on the upper portion of the rear surface side of the front panel 4, and a bearing portion 61 provided on the upper portion of the front housing 3 and rotatably supporting the rotating shaft 60. The pivot shafts 60 are provided at both ends of the front panel 4 in the width direction. The bearing portions 61 are provided at both ends of the front surface case 3 in the width direction and at positions corresponding to the rotation shaft 60. Although not shown in detail, the pivot shaft 60 is provided at the tip of an arm projecting toward the front surface case 3, for example.
The illustrated front panel 4 is a flat surface, but may be a grill having ventilation holes. The rotation mechanism 6 is not limited to the above configuration, and may be of another form as long as the front panel 4 can be rotatably attached to the front surface side of the housing 1.
As shown in fig. 4 to 6, the indoor unit 100 includes an engagement structure 7 for engaging the casing 1 and the front panel 4 with each other. In a state where the front panel 4 is closed, the engaging structure portion 7 engages and fixes the front surface case 3 and the front panel 4. The engagement structure portion 7 includes: a locking protrusion 70 provided on a lower portion of the rear surface side of the front panel 4, and a locking groove portion 71 provided on a lower portion of the front housing 3 and into which the locking protrusion 70 is fitted. The locking projections 70 are provided at both ends in the width direction of the front surface panel 4. The locking groove portions 71 are provided at both ends in the width direction of the front surface case 3 and at positions corresponding to the locking protrusions 70. The engaging structure portion 7 is not limited to the above configuration, and may be in another form as long as the front surface case 3 can be engaged and fixed with the front surface panel 4 in a state where the front surface panel 4 is closed.
The heat exchanger 10 functions as an evaporator to cool air during the cooling operation, and functions as a condenser (radiator) to heat air during the heating operation. Heat exchanger 10 is attached to rear casing 2, is provided in an air passage extending from front surface suction port 30 and upper surface suction port 31 to discharge port 32, and is provided on the upstream side of the blower fan. The heat exchanger 10 may be a plate-fin-tube heat exchanger that can exchange heat between the refrigerant flowing through the refrigerant pipe and the air passing through the fins, for example.
The blower fan sucks in indoor air from the front surface suction port 30 and the upper surface suction port 31, and blows out conditioned air from the blow-out port 32. The blower fan is attached to the rear casing 2, is provided in an air passage from the front surface suction port 30 and the upper surface suction port 31 to the blow-out port 32, and is provided on the downstream side of the heat exchanger 10. The air supply fan may be a cross flow fan, for example.
The electrical component box 11 houses a control device and the like for controlling the indoor unit 100, and is attached to the rear casing 2. The control device is constituted by a microprocessor unit or the like, for example. The drain pan is disposed below the heat exchanger 10, and is provided to receive condensed water generated during operation of the indoor unit 100.
Next, features of the indoor unit 100 of the air conditioner according to the present embodiment will be described. In the indoor unit 100, the engagement structure 7 is released from engagement during maintenance or the like, and the front panel 4 is rotated to open the front surface side of the front casing 3. Here, a finger rest 50 having a concave shape for a user to rest his finger when releasing the engagement structure 7 is formed at a boundary portion between the front panel 4 and the front case 3. The front panel 4 needs to be rotated in order to release the engagement structure 7, but the finger release part 50 is very conspicuous due to its shape, and therefore, there is a problem that the appearance of the indoor unit 100 is impaired. In particular, in the indoor unit 100 in which the front casing 3 has the inclined surface portion 5 and the finger release portion 50 is formed on the inclined surface portion 5, the finger release portion 50 is very conspicuous when viewed from the front surface side, and thus there is a problem that the appearance is very deteriorated.
Therefore, as shown in fig. 7 and 8, the inclined surface portion 5 in the present embodiment is provided with a recessed finger release portion 50 for releasing a finger of a user when the front panel 4 in the closed state is rotated in the opening direction, and the finger release portion 50 has a trapezoidal shape gradually narrowing from the front surface side toward the rear surface side. That is, in the indoor unit 100 of an air conditioner according to the present embodiment, the function as the hands-off finger portions 50 can be ensured by the trapezoidal wide portions, and the presence of the hands-off finger portions 50 can be made as inconspicuous as possible by the trapezoidal narrow portions when viewed from the front surface side, thereby making it possible to present an appearance with excellent appearance.
As shown in fig. 6, the finger placing part 50 is preferably deep enough to allow the user's finger to be placed from the tip of the finger to a position approximately half way along the first joint. This is because if a finger can be inserted from the fingertip to a position about half of the first joint, the finger can be firmly placed on the edge of the front panel 4, and the operation of releasing the engagement state of the engagement structure portion 7 can be eased.
As shown in fig. 8, the finger release part 50 is provided at a position adjacent to the engagement structure part 7. That is, since the force of the user's finger put in the finger put part 50 is directly transmitted to the engaging structure part 7, the engaging state of the engaging structure part 7 can be easily released. However, the finger release part 50 may be provided at a position away from the engagement structure part 7 as long as the engagement state of the engagement structure part 7 can be released.
As shown in fig. 6 to 8, the inner surface side of the case 1 of the finger release part 50 is closed by the engaging structure 7. Specifically, the inner surface side of the finger put-on part 50 is closed by the outer surface of the locking groove part 71 of the engagement structure part 7. Therefore, the indoor unit 100 can prevent wind or dust from entering the inside of the casing 1 through the finger placing part 50, and thus can prevent the cause of a failure.
The present invention has been described above based on the embodiments, but the present invention is not limited to the configurations of the above embodiments. For example, the internal configuration of the indoor unit 100 shown in the drawing is an example, and is not limited to the above, and may include other components. The indoor unit 100 may not have the engagement structure 7. In summary, the present invention includes design changes and a range of changes in application that are conventionally performed by those skilled in the art within a range that does not depart from the technical idea thereof.
