Definitions
- the present invention relates to an indoor unit for an air conditioning device including an opening through which a terminal block can be accessed.
- An indoor unit for an air conditioning device includes a heat exchanger and a fan therein, and includes various types of panels covering the heat exchanger and the fan from the outside (for example, PTL 1).
- a terminal block in which a connection terminal of an electrical system is provided, is provided in the indoor unit for an air conditioning device. It is necessary to form an opening in a front panel at a position corresponding to the front side of the terminal block such that it is possible for an operator to access the terminal block. Then, by making the opening open to a downward direction, accessibility from the downward direction can be improved. However, when the opening is made open to the downward direction, the rigidity of the opening of the front panel decreases.
- an object of the present invention is to provide an indoor unit for an air conditioning device that can suppress a decrease in the rigidity of a front panel even in a case where an opening, through which a terminal block can be accessed, is open to a downward direction.
- the indoor unit for an air conditioning device of the present invention adopts the following means.
- an indoor unit for an air conditioning device including a terminal block that has a connection terminal of an electrical system provided in a main body, a front panel that is positioned on a front side of the main body and has an opening, which is formed on a front side of the terminal block and of which one side is open, and a cover portion that covers the opening and is detachably provided with respect to the front panel.
- the front panel having the opening on the front side of the terminal block By providing the front panel having the opening on the front side of the terminal block, an operator can access the terminal block via the opening. In addition, since there is the opening of which the one side is open, it is easy for the operator to access the terminal block. Since the one side of the opening is open, the rigidity of the front panel decreases. Thus, by providing the cover portion covering the opening in the present invention, a decrease in the rigidity of the opening of the front panel can be suppressed. In addition, the operator can access the terminal block by removing the detachable cover portion.
- the opening of which the one side is open can be formed by providing two protruding portions, which extend from a base end portion to the one side in substantially parallel with each other, in a gate shape.
- a bottom panel that is detachably provided below the front panel and closes the one side of the opening is further included.
- the bottom panel is detachably provided below the front panel, the operator can easily access from below the front panel by removing the bottom panel.
- the bottom panel is provided to close the one side of the opening, the rigidity of the opening can be improved.
- a drain hose connection port is provided at a position where the bottom panel is removed from the front panel.
- drain hose connection port is provided at the position where the bottom panel is removed from the front panel, the operator can access the drain hose connection port by simply removing the bottom panel.
- the cover portion and the bottom panel are independent of each other and are detachably provided with respect to the front panel.
- the cover portion and the bottom panel are independent of each other and are detachable from the front panel. Accordingly, it is not necessary for the operator to remove both of the cover portion and the bottom panel, and it is enough to remove the cover portion or the bottom panel according to operation content.
- the cover portion covering the opening is provided, a decrease in the rigidity of the opening of the front panel can be suppressed even in a case where the opening, through which the terminal block can be accessed, is open to the downward direction.
- Fig. 1 illustrates an appearance of an indoor unit 1 of an air conditioning device.
- the indoor unit 1 is a wall-hanging type, sucks indoor air from above, and blows air after air conditioning indoors from below.
- the indoor unit 1 is connected to an outdoor unit (not illustrated), receives supply of a refrigerant compressed by the outdoor unit, and adjusts indoor air so as to have a predetermined temperature by means of an indoor heat exchanger provided inside the indoor unit 1.
- the indoor unit 1 includes a front panel 3 on a front side so as to cover a main body to which the indoor heat exchanger and a fan is attached.
- the front panel 3 is made of a resin, and is fixed to a base plate (not illustrated) which is fixed to an indoor wall surface.
- a decorative panel 4 is attached in front of the front panel 3.
- Fig. 2 is a perspective view of the indoor unit 1 illustrated in Fig. 1 , which is seen from diagonally below. As illustrated in Fig. 2 , a flap 5 is provided below the decorative panel 4. Air after air conditioning blows by opening the flap 5.
- a resin bottom panel 6 is provided below the flap 5. Although a state where the bottom panel 6 is removed from the front panel 3 is illustrated in Fig. 2 , the bottom panel 6 is fixed to the front panel 3 in an assembled state illustrated in Fig. 1 .
- the bottom panel 6 has the same width as the front panel 3, and claws 6a are provided in both side portions thereof.
- the bottom panel 6 is detachably attached to the front panel 3 by the claws 6a on both sides of the bottom panel 6 engaging with the front panel 3.
- a resin cover portion 7 is provided on the right in a case where the indoor unit 1 is seen from the front as in Fig. 2 .
- a lower end of the cover portion 7 is provided to match an upper end of the bottom panel 6.
- the cover portion 7 is provided to cover the front of a terminal block 8 (refer to Fig. 3 ) in which a connection terminal of an electrical system is provided.
- the terminal block 8 is provided on the left of the indoor unit 1, the cover portion 7 is provided on the left.
- Fig. 3 illustrates a state where the bottom panel 6 and the cover portion 7 are removed from the front panel 3.
- the terminal block 8 is provided on the right of the indoor unit 1.
- a drain hose connection port 9 that is open to a downward direction is provided on the left of the terminal block 8.
- a drain hose (not illustrated) is connected to the drain hose connection port 9. Drain water condensed by the indoor heat exchanger in the indoor unit 1 is led to the drain hose connection port 9.
- the drain hose connection port 9 is easily accessed by removing the bottom panel 6 from the front panel 3.
- the front panel 3 has an opening 10 on the front side of the terminal block 8.
- the opening 10 is formed between a first protruding portion 3a extending from a base end portion of the front panel 3 along a side portion of the front panel 3 and a second protruding portion 3b extending substantially parallel to the first protruding portion 3a at an interval. Therefore, the opening 10 is a window formed in a gate-shaped gap formed by the first protruding portion 3a and the second protruding portion 3b, and one side 10a thereof is open.
- the cover portion 7 is detachably attached to the front panel 3 so as to cover the opening 10. Specifically, a claw (not illustrated) provided on one end of the cover portion 7 is engaged with engaging grooves 3a1 and 3b1 provided in tip portions of the protruding portions 3a and 3b, and the cover portion 7 is rotated about the claw as a rotation center. A claw 7a provided on the other end of the cover portion 7 is fixed by engaging with an engaging groove (not illustrated) of the front panel 3. In this manner, the cover portion 7 is independent of the bottom panel 6 and is detachable from the front panel 3.
- the upper end of the bottom panel 6 is provided to match the lower end of the cover portion 7. Therefore, the one side 10a of the opening 10 is closed by the bottom panel 6 when the bottom panel 6 is attached to the front panel 3.
- the front panel 3 having the opening 10 on the front side of the terminal block 8 an operator can access the terminal block 8 via the opening 10.
- the opening 10 of which the one side 10a is open it is easy for the operator to access the terminal block 8. Since the one side 10a of the opening 10 is open, the rigidity of the front panel 3 decreases.
- the cover portion 7 covering the opening 10 is provided, a decrease in the rigidity of the opening 10 of the front panel 3 can be suppressed.
- the operator can easily access the terminal block 8 by removing the detachable cover portion 7.
- the bottom panel 6 is detachably provided below the front panel 3, the operator can easily access from below the front panel 3 by removing the bottom panel 6.
- the bottom panel 6 is provided to close the one side 10a of the opening 10, the rigidity of the opening 10 can be improved.
- drain hose connection port 9 is provided at a position where the bottom panel 6 is removed from the front panel 3, the operator can access the drain hose connection port 9 by simply removing the bottom panel 6.
- the cover portion 7 and the bottom panel 6 are independent of each other and are detachable from the front panel 3.
