Description

The present invention relates to an air conditioner, and more particularly to an LED display substrate provided in a wall-mounted indoor unit.

Conventionally, the indoor unit of a separate type household air conditioner has a horizontally long rectangular parallelepiped when viewed from the front. (See, for example, Patent Document 1.).

This indoor unit has a structure in which an electrical component box in which a control board for controlling the indoor unit is stored is stored above the front side. Generally, when the width of the indoor unit is narrowed to a compact shape, a structure in which the electrical component box is stored on the front side of the indoor unit is adopted. In this case, a product such as Patent Document 1 which is not equipped with a filter cleaning mechanism can have a structure in which the electrical component box is stored above the front side.

In products equipped with this filter cleaning mechanism, the upper surface of the indoor unit is an indoor air suction port, and the filter is placed here, so the filter cleaning mechanism is inevitably the front of the indoor unit. It will be placed above the side.
Therefore, control units such as an electrical component box, a sensor unit, a remote controller light receiving unit, and an LED display board are provided below the front side of the indoor unit.
On the other hand, the lower part on the front side of the indoor unit is provided with an outlet so as to blow out the conditioned air forward. Therefore, the space in which the above-mentioned control units can be arranged is short in the vertical direction and long in the longitudinal direction (horizontal direction) of the indoor unit.

The space in which the above-mentioned control units can be arranged is very narrow, and each control unit is in a state of being close to each other in the left-right direction, and there is not enough dimensional allowance for arranging the LED display board. In addition, the remote control light receiving part and the sensor unit have a fixed size, and special products with changed dimensions in the left-right direction cannot be adopted because they are expensive. Therefore, in order to arrange all of the above-mentioned control units side by side in the left-right direction of the indoor unit, it is necessary to shorten the dimensions of the LED display board in the left-right direction.

The LED display board is provided with a light guide unit which is a mechanical component that guides light emitted from a plurality of LED display elements provided on the board to the front of the indoor unit. The light guide portion is arranged in close contact with the periphery of the LED display element on the LED display substrate so that the light emitted from the adjacent LED display elements does not leak to each other.
For this reason, there is a problem that the light guide portion becomes an obstacle and the parts cannot be freely arranged on the LED display board, and the dimensions of the LED display board in the longitudinal direction of the indoor unit cannot be shortened.

Further, as described above, the lower side of the indoor unit has a structure that is curved toward the upper side from the rear toward the front, and in the method of vertically arranging the LED display elements, the light of the LED display elements is emitted along the curvature. A light guide unit with a complicated shape that leads to the outside of the indoor unit is required. Therefore, since the cost of the light guide unit corresponding to this curvature increases, this structure cannot be adopted, and as a result, the dimensions of the LED display substrate in the longitudinal direction of the indoor unit cannot be shortened.

Japanese Unexamined Patent Publication No. 2012-207909 (paragraph numbers 0018 to 0028)

Hereinafter, embodiments of the present invention will be described in detail as examples based on the accompanying drawings. The illustration of the outdoor unit not directly related to the present invention will be omitted.

FIG. 1 is an external view of an indoor unit 1 showing an embodiment of an air conditioner according to the present invention.
As shown in FIG. 1, the indoor unit 1 has a rectangular parallelepiped housing having a horizontally long front surface. A suction port 3 is provided in the upper part of the indoor unit 1, and an outlet 4 is provided in the lower part on the front side. Further, a front cover 2 that covers the front surface and the left and right sides of the indoor unit 1 and a base 8 to which the front cover 2 is mounted are provided. Further, the air outlet 4 is provided with a vertical wind direction plate 25, and the vertical air direction plate 25 closes the air outlet 4 when the operation is stopped. The front cover 2, the base 8, and the vertical wind direction plate 25 constitute the outer shell of the housing of the indoor unit 1.

Further, a display window 5 is provided above the air outlet 4 of the indoor unit 1, and five LED elements (not shown) are arranged in the horizontal direction inside the indoor unit 1 corresponding to the display window 5, and these LEDs are arranged. The structure is such that the light of the element is displayed individually. A light receiving window 6 for receiving infrared rays emitted by a remote controller (not shown) is provided on the left side thereof.
Further, the lower side of the indoor unit 1 has a structure that is curved toward the upper side from the rear toward the front, so that the air outlet 4 moves forward when the vertical wind direction plate 25 is rotated about the longitudinal direction. As seen from the front, that is, the air can be blown toward the front of the indoor unit 1.

FIG. 2 is a cross-sectional view of the indoor unit 1 when viewed in the longitudinal direction. In FIG. 2, the left side is the front side of the indoor unit 1, and the right side is the back side (rear) of the indoor unit 1. As shown in FIG. 2, in the ventilation passage between the suction port 3 and the air outlet 4, an inverted V-shaped heat exchanger 21 and indoor air are sucked from the suction port 3, and the heat exchanger 21 sucks the refrigerant and heat. A blower fan 22 is provided to send the air from the air outlet 4 into the room after the replacement.

Further, below the heat exchanger 21, a dew tray 28a and a dew tray 28b for receiving the condensed water dripping from the heat exchanger 21 are provided. Further, in the vicinity of the air outlet 4 inside the indoor unit 1, a plurality of left and right wind direction plates 27 for deflecting the sent air in the left-right direction are provided, and the air outlet 4 is provided with rotation in the longitudinal direction of the indoor unit 1. A vertical wind direction plate 25 that rotates about the shaft 25a is provided.

A base 8 for fixing main parts such as a heat exchanger 21 and a fan motor (not shown) is on the back side (right side of FIG. 2) of the indoor unit 1, and a suction grill 29 is on the upper surface of the indoor unit 1 for heat exchange. A filter 24 is provided between the vessel 21 and the suction grill 29, respectively.

A filter cleaning unit 23 is arranged above the front surface inside the housing of the indoor unit 1 to wind up the filter 24 and clean the dust adhering to the surface of the filter 24. The lower part of the filter cleaning unit 23 is a motor unit 23a containing a motor for winding the filter 24. Since the filter 24 is arranged on the upper surface of the indoor unit 1 as described above, the filter cleaning unit 23 for cleaning the filter 24 is inevitably arranged above the front side inside the housing of the indoor unit 1. .. As a result, the filter cleaning unit 23 occupies the upper half of the inside of the housing of the indoor unit 1 on the front side.

As described above, the lower side of the indoor unit 1 has a structure that is curved toward the upper side from the rear toward the front, and the filter cleaning unit 23 in the housing, the heat exchanger 21, the vertical wind direction plate 25, and the housing An electrical component box 26 having a trapezoidal cross section seen in the longitudinal direction of the housing and arranged in the longitudinal direction of the indoor unit 1 is arranged in a space surrounded by a part on the front surface side. The upper surface portion 26e of the electrical component box 26 is arranged so as to face diagonally forward and downward of the indoor unit 1. That is, when the user looks up at the indoor unit 1, the electrical component box 26 is arranged so as to face the upper surface portion 26e of the electrical component box 26.

As described above, the electrical component box 26 has a trapezoidal cross section, and the surface of the electrical component box 26 including the trapezoidal lower bottom is the lower surface portion 26b, and the surface of the electrical component box 26 including the upper bottom is the upper surface portion 26e, respectively. Call it. Further, since the electrical component box 26 has a trapezoidal cross section, the surfaces of the electrical component box 26 including a pair of trapezoidal legs are referred to as an inclined portion 26f and an inclined portion 26c.
Since the inclined portion 26f in contact with the upper surface portion 26e is substantially parallel to the vertical wind direction plate 25 and the inclined portion 26f does not interfere with the vertical wind direction plate 25, the vertical wind direction plate 25 is arbitrarily extended to the front side of the indoor unit 1. Can be made to.

Further, since the inclined portion 26c is provided, it does not interfere with the filter cleaning portion 23 or the front cover 2. Therefore, the length of the side of the lower surface portion 26b of the electrical component box 26 corresponding to the trapezoidal lower bottom described above can be increased. Therefore, a large space for the electrical component box 26 can be secured.
As described above, since the electrical component box 26 is provided with the inclined portion 26f and the inclined portion 26c, the electrical component box 26 can be arranged inside the lower part on the front side of the indoor unit 1. Therefore, the electrical component box 26 does not interfere with the ventilation, and the height of the indoor unit 1 can be lowered.

On the other hand, an LED display unit 30 is provided on the back side (inside the housing) of the display window 5. The LED display unit 30 includes a light guide unit 37 arranged between the LED display board 31, the LED display board 31, and the display window 5 which is a part of the front side of the housing.
The LED display board 31 is arranged on the front side inside the housing above the vertical wind direction plate 25 below the filter cleaning unit 23 in the housing. A plurality of LED display elements (not shown) are arranged on the surface of the LED display board 31 in the longitudinal direction of the indoor unit 1 and emit light toward the front of the indoor unit 1. The LED display unit 30 will be described in detail later.

FIG. 3 is a view of the front surface of the indoor unit 1 with the front cover 2 and the filter cleaning unit 23 removed. All the main parts of the indoor unit 1 are fixed to the base 8.
The LED display unit 30, the remote control light receiving unit 50, the floor temperature sensor 51, the electrical component box 26, and the electrical component box 20 for power supply, which are the main control units, are located in the lower left-right direction (longitudinal direction) on the front side of the indoor unit 1. They are arranged side by side. These are close to each other in the left-right direction, and there is no dimensional allowance for adding new units. The LED display unit 30 is provided with a light guide unit 37 in front of the LED display substrate 31.

Further, since the LED display unit 30, the remote controller light receiving unit 50, and the floor temperature sensor 51 need to be directed diagonally forward and downward from the indoor unit 1, if they are arranged in another place, for example, the upper part of the indoor unit 1, they are placed. A separate structure is required in which the unit is directed diagonally forward and downward from the indoor unit 1.
Further, with respect to the electrical component box 26 and the electrical component box 20 for power supply, there is a problem that the size of the indoor unit 1 becomes large if a space that can be arranged in a place other than the lower part on the front side of the indoor unit 1 is secured, and the electrical component box 26 The indoor unit 1 can be miniaturized by arranging the electrical component box 20 for power supply and the electric component box 20 below the front side of the indoor unit 1.

FIG. 4 is a perspective view of the electrical component box 26, showing a state in which the cover 26a of the electrical component box 26 is removed. The upward arrow A in FIG. 4 indicates a diagonally downward direction on the front side when attached to the indoor unit 1. The right arrow B in FIG. 4 indicates the upper direction of the indoor unit 1, and the left arrow C in FIG. 4 indicates the lower direction of the indoor unit 1.

As described above, the electrical component box 26 has a trapezoidal cross section, and has a shape that is long in the left-right direction along the longitudinal direction of the indoor unit 1. The electrical component box 26 is composed of a cover 26a and a lower surface portion 26b, and a control board 40 is housed inside the cover 26a. The upper surface of the cover 26a is the upper surface portion 26e, the portion of the upper surface portion 26e adjacent to the arrow C side is the inclined portion 26f, and the portion of the upper surface portion 26e adjacent to the arrow B side is the inclined portion 26c. ..

A noise filter 41, a rectifier 42, a film capacitor 43 for noise removal, a switching transformer 44, an electrolytic capacitor 45 for high voltage, and the like are arranged on the control board 40. A circuit block whose right half from the center in the longitudinal direction of the control board 40 handles a relatively high voltage is called a high voltage block, and a circuit block whose left half handles a relatively low voltage is called a low voltage block. The above-mentioned parts are arranged in the high-voltage block, and an AC power supply circuit and a circuit having a relatively high voltage obtained by rectifying the AC power supply circuit are arranged. A circuit with a relatively low voltage is arranged, in which a microcomputer, a relay drive circuit, an integrated circuit, etc. are arranged.

The electrolytic capacitor 45 has a cylindrical shape, and an explosion-proof valve 45a is provided on one end surface thereof. The explosion-proof valve 45a automatically opens to reduce the internal pressure when an abnormal voltage is applied to the electrolytic capacitor 45 and the internal pressure exceeds a certain value to prevent the electrolytic capacitor 45 from exploding. be. When the explosion-proof valve 45a is opened, the electrolytic solution inside flows out and the pressure in the electrolytic capacitor 45 is released.

FIG. 5 is a top view showing a control board 40 housed in the electrical component box 26. The upper direction of FIG. 5 is the upper direction of the indoor unit 1, and the lower direction of FIG. 5 is the lower direction of the indoor unit 1. In addition to the high-voltage block / low-voltage block classification described above, the control board 40 has two types of blocks classified according to the height of the component in the longitudinal direction of the control board.
Of these, the area where the short parts are arranged is called a low-rise block, and the area where the tall parts are arranged is called a high-rise block.

As shown in FIG. 5, the high-rise block is a block sandwiched by two broken lines described in the longitudinal direction, and corresponds to the projection surface of the upper surface portion 26e of the cover 26a described above. That is, since the high-rise block is the portion of the electrical component box 26 where the distance between the cover 26a and the lower surface portion 26b is the longest, tall parts such as a noise filter 41, a rectifier 42, and noise removal are used here. The film capacitor 43, the switching transformer 44, and the like are arranged.

On the other hand, the low-rise block is an area where relatively short parts are arranged. The upper low-rise block in FIG. 5 is an area corresponding to the projection surface of the inclined portion 26c, and the lower low-rise block in FIG. 5 is an area corresponding to the projection surface of the inclined portion 26f.
For example, in the low-rise block in the area corresponding to the projection surface of the inclined portion 26f of the high-voltage block, a cylindrical electrolytic capacitor 45 is laid down in the longitudinal direction of the control board 40. As described above, since the electrolytic capacitor 45 is provided with the explosion-proof valve 45a, if the explosion-proof valve 45a is opened, the electrolytic solution 45b may flow out.

When the control board 40 is stored in the electrical component box 26 and fixed to the indoor unit 1, the electrolytic capacitor 45 is arranged so that the electrolytic solution 45b flows toward the lower part of the indoor unit 1. Therefore, by any chance, the electrolytic solution 45b Even if it flows out, it does not adhere to other parts in the control board 40, so that it is possible to prevent secondary damage to the parts due to the electrolytic solution 45b.

Further, by dividing the control board 40 into high-pressure / low-pressure blocks and arranging the components, it is possible to easily clear the safety standard based on the creepage distance. Further, by dividing the control board 40 into high-rise / low-rise blocks and arranging the components, the space inside the electrical component box 26 can be effectively used, and the electrical component box 26 can be made smaller. Therefore, the electrical component box 26 can be arranged on the lower side in front of the indoor unit 1.
Further, since the electrical component box 26 is provided with the inclined portion 26f, the dimension of the vertical wind direction plate 25 in the depth direction can be lengthened along the inclined portion 26f, whereby the ventilation performance can be improved.

FIG. 6 is a top view showing the LED display unit 30. The left-right direction in FIG. 6 corresponds to the left-right direction when the LED display unit 30 is mounted on the indoor unit 1. The LED display unit 30 is arranged on a rectangular LED display board 31 having a long side in the longitudinal direction and a short side in the lateral direction of the indoor unit 1, and light from the LED display element 33 is emitted from the indoor unit 1. A light guide unit 37 for guiding the light guide to the outside of the housing is provided.
The LED display board 31 uses a single-sided printed circuit board, and the pattern surface is a component surface (surface) because surface mount components are used. Further, when the LED display unit 30 is fixed to the indoor unit 1, the pattern surface faces diagonally downward in front of the indoor unit 1. Therefore, the LED display element 33, which will be described later, soldered to the pattern surface also faces diagonally downward in front of the indoor unit 1, that is, toward the user.

The connector 32 is arranged at the center on the left and right of the upper end (upward direction of FIG. 6) of the LED display board 31 of FIG. It is placed facing you. The circuit unit 35 is a series circuit of the LED display element 33 and the resistor 34. One end of the resistor 34 is connected from each terminal 32a of the connector 32 via the LED display element 33, and the other end of the resistor 34 is connected to the terminal of the connector 32 via the power supply pattern 36.
Each signal for driving the plurality of LED display elements 33 and an external circuit of the LED display board, for example, a plurality of connection points (each terminal 32a of the connector 32) for connecting the control board 40 are the lengths of the LED display board 31. It is arranged along the side.

As shown in FIG. 6, the five LED display elements 33 are arranged at equal intervals in the left-right direction on the LED display board 31. Then, a light guide portion 37 made of a rectangular parallelepiped made of resin is mounted so as to cover these LED display elements 33. The light guide unit 37 includes a light passing hole 37a formed of a cylindrical space corresponding to the position of each LED display element 33.
The light guide unit 37 guides the light emitted by the LED display element 33 to the front of the LED display element 33, and prevents the light emitted by the adjacent LED display element 33 from leaking to the adjacent light passage hole 37a. It is something to do. Therefore, the light guide unit 37 is arranged in close contact with the LED display substrate 31 and the display window 5 of FIG.

As described with reference to FIG. 3, the LED display unit 30, the remote control light receiving unit 50, the floor temperature sensor 51, which are the main electronic units, are the main electronic units in the left-right direction below the front side of the indoor unit 1 from the right side to the left side. The electrical component box 26 and the power supply electrical component box 20 are arranged side by side in this order. These are in a state of being close to each other in the left-right direction. The remote control light receiving unit 50 and the floor temperature sensor are purchased parts from the respective manufacturers, and special products whose dimensions are changed in the left-right direction cannot be adopted because they are expensive.
Therefore, the LED display unit 30 needs to be as short as possible in the left-right direction.

In order to minimize the horizontal dimension of the LED display unit 30, it is necessary to minimize the horizontal dimension of the light guide unit 37, that is, the light passing holes 37a must be arranged so as to be closest to each other in the horizontal direction. be. There is also a method of arranging five LED display elements 33 vertically, but arranging them in the left-right direction is more harmonious in terms of design. Further, as described above, the lower side of the indoor unit 1 has a structure that is curved toward the upper side from the rear toward the front. Therefore, in the method of arranging five LED display elements 33 vertically, a light guide portion having a complicated shape that guides the light of the LED display elements to the outside of the indoor unit along the curve is required. This structure cannot be adopted because the cost of the light guide portion corresponding to this curvature increases.

As described above, the LED display board 31 is provided with a light guide unit 37 which is a rectangular parallelepiped made of resin and guides light emitted from a plurality of LED display elements 33 provided on the board to the front of the indoor unit 1. The light guide unit 37 is arranged in close contact with the periphery of the LED display element 33 so that the light emitted from the adjacent LED display elements 33 does not leak to each other.
Therefore, components such as the resistor 34 and the connector 32 cannot be arranged on the surface of the LED display board 31 that is in close contact with the light guide portion 37. Therefore, as shown in FIG. 6, the LED display board 31 is provided with a plurality of connection points for connecting each signal for driving each LED display element and the external circuit (control board 40) of the LED display board 31. The connector 32 is arranged along the long side of the LED display board 31.
Further, the circuit units 35 are arranged downward in FIG. 6, and the required number of the circuit units 35 are arranged in the horizontal direction, that is, they are electrically connected to each LED display element and each LED display element in series. By arranging the parts, for example, each resistor along the short side of the LED display board 31, it is possible to correspond to the dimension in which the light guide portion 37 described above is minimized in the left-right direction.
As a result, the above-mentioned main electronic units can be arranged in the lateral direction of the indoor unit 1.

In this embodiment, the connector 32 is arranged along the long side of the upper end of the LED display board 31, but the present invention is not limited to this, and a place other than the left and right sides of the LED display board 31, for example, the LED display board 31 The connector 32 may be arranged along the long side of the lower end of the LED. Alternatively, a directly attached lead wire may be connected instead of the connector.

In this embodiment, the cross section of the electrical component box is trapezoidal, but the cross section is not limited to this. An electrical component box having a cross-sectional shape may be used.
Further, in the present embodiment, the electrical component box is provided with a cover and a lower surface portion, but the present invention is not limited to this, and a structure corresponding to the cover and the lower surface portion may be included in the internal structure of the indoor unit.

In this embodiment, the electrical component box and the LED display unit are separate units, but the present invention is not limited to this, and the LED display unit may be provided in the electrical component box. Since the upper surface of the electrical component box is arranged so as to face diagonally forward and downward of the indoor unit, it is easy for the user to visually recognize the light emission of the LED display element when looking up at the indoor unit. In addition, a member that electrically connects the electrical component box and the LED display unit is not required, and the cost can be reduced. Further, it is not necessary to arrange the LED display units independently, and the length of the electrical component box in the left-right direction can be increased by this space to provide a wider board space.
