(B) Prior Art Generally, the control board of a control unit module attached to a rotating machine used in a humid environment is subjected to a moisture-resistant treatment (see Japanese Patent Application Laid-open No. 158693/1983). The reason for this is that when water droplets adhere to the control board, they cause damage between the lead terminals of electronic components mounted on the control board.
Or a short circuit may occur between conductor patterns, resulting in malfunction of the control circuit.
This is to prevent malfunctions such as breakdowns from occurring.

A control circuit consisting of a resistor, a capacitor, a microcomputer, a triac that generates heat, etc. is mounted on the control board, and when it receives an input signal from the outside, it controls the drive motor of the rotating machine based on the signal.

19) is screwed in multiple places and attached to the rotating machine.

(c) Problems to be Solved by the Invention In general, a printed circuit board is mainly used as the above-mentioned control board. The printed circuit board on which the circuit for driving and controlling the main parts of the rotating machine is formed is designed to be as large as possible in order to minimize the storage space required for installation on the rotating machine/JX type. is common. However, in recent years, the number of circuit elements and electronic components that can be mounted on a printed circuit board has increased due to the increasing functionality of rotating machines as they have become more sophisticated. Since this is desired, there are certain restrictions on the size of the printed circuit board. Therefore, pattern wiring was formed on the board and components were mounted without taking into consideration the component placement and pattern wiring.

As a result, (1) it becomes extremely vulnerable to self-noise, resulting in the problem of noise-induced malfunctions.

(2) As mentioned above, since there are restrictions on the board size, there are many cases where the routing lines of the wiring pattern that connects a large number of electronic components etc. become thin and breakage occurs, resulting in the control board itself being defective.

■It becomes difficult to lead the lead wires for connection to the main parts of the rotating machine from a fixed position on the printed circuit board, for example, many lead wires are placed near relatively tall electronic components mounted on the printed circuit board. There was a problem that the work was difficult when it was extracted and installed.

In addition, in the conventional control unit module, the control board (
Since electronic components consisting of a large number of discrete components are mounted on a printed circuit board (printed circuit board) by soldering, the number of solder connection points becomes extremely large, and the post-processing process after soldering becomes complicated, reducing work efficiency. there were.

Furthermore, in conventional control unit modules, the board and other electronic components are completely coated with urethane resin to protect the connections of electronic components mounted on the control board from moisture, which reduces the weight of the control unit module. It gets heavy. As a result, when the switch means is integrally formed in the module, even if the module is fixed to the rotating machine with screws, the weight of the module itself weakens the screw fixing force over time, resulting in poor switch operation. Furthermore, there is a problem in that the cost increases because a large amount of urethane resin is used.

Furthermore, when a conventional control unit module is installed in a rotating machine such as a washing machine, the shape of the control board is elongated due to the structure of the washing machine, so if the board is completely coated with urethane resin, the board and urethane resin will be separated. As a result, the substrate is distorted due to temperature changes due to the significant difference in the expansion coefficient α of
There is a problem in that cracks occur in the solder joints of electronic components mounted on a board, increasing the defective rate.

Finally, conventional control unit modules have a major problem in that when the heating elements such as triacs that drive the motors of rotating machines break down due to short circuits, they catch fire, causing the urethane resin and surrounding parts to catch fire, resulting in fires. Ta.

(d) Means for Solving the Problems The present invention has been made in view of the above-mentioned problems, and is a control unit module tear installed in a rotating machine driven by a motor and used in a relatively humid environment. A hybrid IC in which at least a circuit for driving and controlling the rotating machine is integrated on an insulating substrate and a large electrical component are mounted on a control board of the control unit module, and the hybrid IC and large electric components mounted on the control board are mounted on the control board of the control unit module. It is also characterized in that the mounting heights of large electrical components are arranged at approximately the same height.

(*) Effect As described above, according to the present invention, the control board is mounted on the control board of the control unit module by mounting a hybrid IC in which a circuit for driving and controlling the rotating machine is integrated on an insulating board. Since it is not completely coated with water-resistant resin such as urethane as in the past, the amount of water-resistant resin used can be reduced by 40 to 60% compared to the past. As a result, the weight of the unit module is significantly lighter than before, and the impact on cost is also significant.

Further, since the circuits conventionally mounted on the control board are integrated into the hybrid IC and mounted on the control board, the size of the control board can be significantly reduced. As a result, distortion due to bending of the control board does not occur, and cracks can be prevented from forming in the solder joints of the components mounted on the control board.

Furthermore, in the present invention, the mounting heights of the hybrid IC mounted on the control board and the large electrical component are approximately the same, so that the storage space when mounting on the rotating machine can be formed uniformly and thinly.

(F) Embodiments The control unit module of the present invention will be explained below based on the embodiments shown in FIGS. 1 to 6.

FIG. 1 is a plan view of the control unit module (hereinafter simply referred to as module) (1) of the present invention, and FIG.

), an electronic buzzer (7), a capacitor (6), and other relatively large electronic components and a hybrid IC (5) that integrates main circuits, and a connector (8) are mounted to drive and control the main parts of the rotating machine.

As mentioned above, in the field of rotating machines, as the machines become more sophisticated, rotating machines that are smaller and have multiple functions have become mainstream. Figure 3 is a plan view showing the operating parts of a typical washing machine that uses a wet environment, where (27) is the wash time setting button, (28) is the rinse frequency setting button, and (29) is the Dewatering time setting button, (20) is the water flow intensity setting button, (21) is the selection button for whether or not to perform water rinsing, (22) is before setting the standard course or the favorite course where you manually enter each process time. The start button (23) is a start button before setting a speedy course that completes the entire process in 23 minutes, and (24) is a stop button for stopping at -. Each of the various operation buttons corresponds to an LED, which is turned on and off as appropriate depending on the operation. Also,(
25) is a display section of the water temperature rank detected by the temperature detection device, and corresponding to the display of high temperature, medium temperature, and low temperature,
E D (26a), (26b), and (26c) are lit. A circuit for driving and controlling each button and LED display is formed on the substrate (3), and the circuit configuration tends to become increasingly complex.

By the way, one feature of the present invention is that the main circuits for driving and controlling the rotating machine are integrated into a hybrid IC and mounted on the control board (3).

Substrate of hybrid rC (5) used in this example (
5g) and (5b) (hereinafter simply referred to as an IC substrate), an aluminum substrate which has been insulated can be used.

Although it is possible to use a substrate made of ceramics, glass epoxy, etc. other than the aluminum substrate, an aluminum substrate is used in this embodiment because there is a circuit portion that is relatively heat-generating.

An insulating resin layer (not shown) such as epoxy or boimide resin is provided on the IC substrate (5a) (5b), which is attached to the structure of the IC substrate (5a) (5b). A conductive path (5c) of a desired shape is formed on the upper surface of the copper foil.

On one IC board (5a) is a circuit element (5d) that generates heat, such as a power supply circuit consisting of a plurality of triac elements and a plurality of rectifier diodes that drive the motor of a rotating machine.
is mounted on the other IC board (5b), and a plurality of circuit elements (5e) constituting a control circuit such as a microcomputer that controls a motor of the rotating machine and a predetermined portion are mounted on the other IC board (5b).

Circuit elements (5) mounted on IC boards (5a) (5b)
d)<5e) are all mounted in chip form, and elements such as printed resistors, chip resistors, chip capacitors, etc. can be mounted on the respective substrates (5g) (5b) as required. Furthermore, a plurality of external lead terminals (5x>(5Y)) are led out from the negative peripheral edges of both IC boards (5a)<5b) and are soldered connected to the conductor pattern (3a) of the control board (3).Both ICs In order to achieve another object of the present invention, the external lead terminals (5z) (5y) that can be completely led out from the substrates (5a) (5b) are bent at a substantially right angle after being led out in the horizontal direction.

By the way, both IC boards (5a) (5b) are made of arboreal case material (
5x), and are firmly fixed.

In addition to the hybrid IC <5>, large electronic components such as a transformer (4), a capacitor (6), and a connector (8) are mounted on the control board (3), and the conductor pattern (3a) of the board (3) It is soldered connected to the transformer (4
) converts the voltage, for example converts ACIoov to 10■, and the capacitor (6) is a hybrid IC.
It rectifies the output voltage of (5), and the connector (8
> is connected to the switch input board.

On the other hand, another feature of the present invention is that the mounting height between the mounting surface of the hybrid IC (5) and the mounting surface of large electrical components such as the transformer (4) and the capacitor (6) is approximately the same. It's there. In the present invention, a hybrid IC
(5) is arranged horizontally. That is, the IC substrate (5a) (5b) surface of the hybrid IC (5) and the control substrate (
3) Arranged so that the planes are parallel to each other.

In this embodiment, considering the heat generation in the power system, a small signal system IC is used.
Although the board (5b) is selectively placed on the control board (3) side, the power system IC board (5a) may be placed on the board<3) side. In this case, it can be expected that the moisture in the module (1) caused by the heat generated by the power system board (5a) can be dried.

By the way, the control board 3) has a plurality of slit holes <10
) and holes (9a) (9b) are provided. The slit hole (10) is provided around the hybrid IC (5), that is, the lead terminals (5x) (5Y), and the slit hole (10) causes the control board (3) to undergo strain due to stress, etc. Hybrid IC
The stress caused by the strain is absorbed to some extent by the external lead terminals (5x) (5y) of <5>, and the stress caused by the strain is absorbed by the external lead terminals (5x) (5y).
) (5y) and the substrate (3) to prevent cracks from occurring at the solder joint. In addition, the plurality of holes <9a) (9b) are for leading out lead wires (not shown) for power and small signals, and the holes (9a) (9b) for power and small signals are for leading out lead wires (not shown) for power and small signals. They are arranged so that they are separated from each other by a predetermined distance. As described above, it is more convenient for the work to arrange the lead wires in one block at a predetermined distance from each other when connecting to each main part of the rotating machine.

In the present invention, the main circuit is a hybrid ■C (5)
Since the control board (3) is integrated within the control board (3), only a few things are mounted on the control board (3), such as a hybrid IC (5), a transformer (4), a capacitor (6), and a connector (8). Therefore, the conductor pattern (3a) formed on the control board (3) requires only a minimum number of routing tabs, so that the conductor pattern (3a) can be set efficiently.

As a result, without increasing the size of the control board (3), the holes (9a) and (9b) for lead wires can be used for power,
It becomes possible to separate the signal for small signals and provide it as desired.

A control board (3) on which mounted components such as a hybrid IC (5) are mounted is placed in a box-shaped frame member (2). When the control board (3) is placed on the frame member (2), the frame member (2)
A predetermined space is provided between the board (3) and the frame member (2) by the spacer (2a), and the board (3) is connected to the locking part (2b) provided on the frame member (2). It is locked by.

By the way, when placing the board (3) on the frame member (2),
The frame member (2) is filled with a coating resin (11) for moisture resistance such as urethane. This coating resin (
11) is a coating resin (11) so as to fill only the space formed by the substrate (3) and the frame member (2).
) amount is set. That is, coating resin (11)
The conductor pattern (3a) and the solder joints (5Z) between each mounted component and the conductor pattern (3a) are protected by
), it is only necessary to fill the space marked with "2" with the resin (11). In this example, the coating resin (
11) is filled with the conductor pattern (3a) of the substrate (3).
and each joint portion is reliably protected by the resin (11).

If you want even more reliable protection, use coating resin (11)
It is a good idea to increase the amount a little. In this case, the excess resin flows out from the gap between the substrate (3) and the side surface of the frame member (2), but there is no problem.

In this example, a hybrid IC mounted on the substrate (3)
The above-mentioned resin <1 la) is selectively provided only on the lead terminals (5x) and (5y) of (5).

As mentioned above, the hybrid IC (5) is composed of two IC boards (5a) (5b), and each IC board (5a)
(5b) to multiple external lead terminals (5x) (5y)
is bent and derived as described above. Since the pitch of each external lead terminal (5x) (5y) is very narrow, there is a risk of short-circuiting due to water droplets unless resin coating is applied.

In the conventional structure, the entire control board 3) was completely covered with the coating resin, but in the present invention, only the external lead terminals (5x) (5y) are coated with the resin (lla) as described above. The resin (lla) that covers the external lead terminals (5x) (5y) can be made relatively easily by placing a formwork and pouring the resin (lla), or by setting the coating resin (lla) to maintain a certain degree of viscosity. The external lead terminals (5x) (5y) can be coated with resin (lla).

Transformer (4), capacitor (6), connector (8) other than hybrid IC (5) mounted on control board (3)
) and other large parts have large distances between lead terminals, so there is no risk of short circuits caused by water droplets, etc., so large parts such as resin (l
There is no need to cover la). However, water resistance can be further improved by selectively applying resin (lla) to each lead terminal of each component. Also, although the lead terminals of the connector (8) are not shown, since the number of terminals is relatively large,
It is better to fill with JI(lla).

Further, in the present invention, as described above, the hybrid IC (5) mounted on the substrate (3) is mounted and arranged parallel to the substrate (3), so the substrate (3) overlaps with the hybrid IC (5).
) on which small discrete components such as resistors and capacitors can be mounted. However, these parts can be easily subjected to moisture resistance treatment by simply selectively pouring the coating resin (lla) into the space between the hybrid IC (5) and the substrate (3).

In this embodiment, as described above, discrete components are mounted on the substrate (3) that overlaps with the hybrid IC (5), but this is selected according to the needs of the user, and therefore the hybrid (2) The C(5) and the substrate (3) may be arranged so as to be substantially in contact with each other.

In this way, the control unit module (1) is completed. Such a module <1> has a frame member (
It is screwed and fixed with the screw part (2c) of 2).

When this type of module (1) is attached to a rotating machine such as a washing machine, a switch board having various input switches is arranged on the structurally exposed surface side of the module (1) of the washing machine. The switch board and control board <3) are flexible lead I! (not shown) and are connected to each other via a connector (8).

FIG. 4 shows a switch base 1 (30) formed for various input switches, in which conductive contact portions formed on a flexible film are arranged facing each other through an opening of an insulating spacer. Further, (31) is a band-shaped flexible lead wire that connects the switch board (30) and the control board (3).

The number of switches that can be formed on the switch board (30) increases as the functionality increases. For example, if as many switches as the input switches shown in FIG. 3 are formed, the switch board will not be raised due to the structure of the washing machine and will have an elongated shape. Therefore, if the switch board is longer than the control board (3) of the module (1), even if the module is screwed into the washing machine, it will definitely have the switch function in the area where it overlaps with the board (3). However, since the switch board is not supported in the non-overlapping area, a problem occurs in which the switch board cannot operate even though it has a switch function.

Therefore, the frame member <2> of the module used in this embodiment is formed longer than the control board (3). That is, it is set to have approximately the same length as the switch board (not shown). In Fig. 5, (2X) shows the outer frame of the frame member (2), (2c) is the screwed part for fixing it to the washing machine, and the part shown by the dotted line is the part of the frame member (2). This is a reinforcing part (2y) to assist deformation. This reinforcement part (2y
) is not clearly shown in the figure, but is formed on the outer surface of the frame member (2), and the switch board is arranged on that surface.

Further, the control board (3) is arranged in the shaded area, and the above-mentioned moisture resistance treatment can be applied thereto.

FIG. 6 is a sectional view when the module of the present invention is installed in a washing machine, in which (1) is the control unit module of the present invention, (2) is the frame member constituting the module (1), and (3) is the control unit module of the present invention.
(5) is the control board, (5) is the hybrid IC1 (11) is the coating resin, (160) is the operation part to which the module (1) is screwed and fixed, (200) is the operation part (160) to which the module (1) is screwed and fixed. ) is a top plate of a washing machine that has a frame that houses the washing machine and forms the clothes input port of the washing machine. Each component is the same as in FIG. 7 of the conventional example, so the same reference numerals are used. Therefore, explanation of each part will be omitted.

According to the present invention, a hybrid IC in which a minimum circuit for driving and controlling a rotating machine is integrated on an insulating substrate is mounted on the control board of a control unit module, so that the control board can be replaced with the conventional one. Since it is not completely covered with a water-resistant resin such as urethane, the amount of water-resistant resin used can be reduced by 40 to 60% compared to conventional methods. As a result, the weight of the unit module is significantly lighter than before, and the impact on cost is also significant.

Further, since the circuits conventionally mounted on the control board are integrated into the hybrid IC and mounted on the control board, the size of the control board can be significantly reduced. As a result, distortion due to bending of the control board does not occur, and cracks can be prevented from forming in the solder joints of the components mounted on the control board.

Furthermore, in the present invention, by arranging the mounting heights of the hybrid IC and the large electrical component to be approximately the same, it is possible to reduce the storage space when mounting the hybrid IC on a rotating machine.

(g) Effects of the Invention As detailed above, according to the present invention, the amount of coating resin for moisture resistance can be significantly reduced. As a result, the weight of the control unit module itself can be made lighter than before, and when the module is installed in a rotating machine (washing machine), the switch board can be firmly fixed, so the screwing part will not be affected by the weight of the module. No more loosening,
This has the advantage that the switch operation can be performed stably regardless of changes over time.

Further, in the present invention, since the external lead terminals of the hybrid IC are selectively coated with resin, the amount of coating resin can be significantly reduced as described above, resulting in a large cost effect.

Furthermore, in the present invention, the vibration knot I mounted on the control board
By making the mounting heights of C and the large military component substantially the same, the module itself can be made thinner. As a result, since the storage space for installing the rotating machine can be reduced, it can contribute to downsizing of the rotating machine.

Furthermore, in the present invention, since the main circuits are integrated within the hybrid IC, the number of components mounted on the control board can be significantly reduced. As a result, the size of the control board can be reduced, and the width of the conductor pattern formed on the control board can be formed to a certain degree uniformly and wide, and defects caused by disconnection of the conductor pattern, which are conventional, can be extremely suppressed.

Furthermore, in the present invention, as described above, the main circuit is a hybrid I.
By integrating the control board into C, a hole for lead wires can be provided at any position on the control board, and each of the power and small signal lead wires can be led out at a predetermined distance apart. Improves work efficiency when connecting lead wires.

Furthermore, in the present invention, by providing a slit hole in the control board around the hybrid IC mounted,
Even if distortion occurs on the control board, stress due to the distortion is not directly applied to the joints of the external lead terminals of the Vibe-Knot IC, so cracks do not occur in the solder joints of the external lead terminals, improving reliability. can.

Furthermore, in the present invention, since the main circuits are integrated into a hybrid IC having a metal substrate, noise resistance and heat dissipation are excellent, and reliability of the control unit module is improved.

Furthermore, in the present invention, since the hybrid IC having a metal substrate is mounted on the module as described above, the heat generated when the hybrid IC dissipates heat has the effect of drying the surrounding moisture.
