  An engagement claw 100 (claw portion) that is engaged with an engagement receiving portion 113 (see FIG. 10B) of the control board 33 to be described later is slightly inside from both ends in the lateral direction of the back surface of the accommodation portion 58. The housing portion 58 is formed integrally with the rear portion 58 so as to protrude rearward from the rear surface. The liquid crystal cover 36 can be attached to the control board 33 by engaging the engagement claw 100 with the engagement receiving portion 113. An opening 99 (forming hole) is formed around the engaging claw 100 by positioning the engaging claw 100 using a jig when the engaging claw 100 is formed, for example. Around this opening 99, an enclosure wall 121 (molded hole enclosure wall) is formed that surrounds the opening 99 and protrudes from the back surface of the accommodating portion 58. As a result, the entrance of the flow path to the outside through the opening 99 in the liquid crystal cover 36 becomes the opening of the front end portion 123 of the enclosure wall 121.

  A plurality of (for example, six in this embodiment) support members 97 are formed on the back surface of the accommodating portion 58 at a predetermined interval. The support member 97 is a base for supporting the liquid crystal cover 36 on the control substrate 33, and is formed in a columnar shape, for example.

Further, one of the support members 97 is provided with a protrusion 110 that is used for positioning the liquid crystal cover 36 with respect to the control substrate 33. With the liquid crystal cover 36 attached to the control board 33, the protrusion 110 is fitted into a fitting hole (not shown) of the control board 33.

In addition, a boss 124 is formed at a substantially central portion on the back surface of the housing portion 58, and a screw hole 105 is formed at the center of the boss 124. The screw hole 105 is a hole for screwing a screw 115 (see FIG. 10C) for fixing the liquid crystal cover 36 and the control board 33.
Further, a groove 87 dug into a substantially semicircular cross section along the outer periphery of the housing portion 58 is formed. The groove 87 is a space for packing the packing 68.

  The switch part 59 is disposed on both the left and right sides of the accommodating part 58. As described above, the reservation key 146 is formed on the left switch part 59, and the key 145 is formed on the right switch part 59. ing. The switch portion 59 is formed with engaging claws 103 that protrude rearward from the back of both the left and right sides. The engagement claw 103 is engaged with an engagement receiving portion (not shown) of the control board 33 in the same manner as the engagement claw 100.

8A and 8B are diagrams showing the configuration of the liquid crystal case 37, in which FIG. 8A is a perspective view of the liquid crystal case 37 as viewed from diagonally upward to the right, FIG. 8B is a front view, and FIG. c) is a bottom view, FIG. 8 (d) is a left side view, FIG. 8 (e) is a right side view, and FIG. 8 (f) is a rear view.
The outer periphery of the liquid crystal case 37 is formed to be substantially the same size as the inner periphery of the accommodating portion 58 of the liquid crystal cover 36, and has a horizontally long, substantially rectangular parallelepiped shape with the front face open.

  A groove 106 is formed at the center of the lower edge of the liquid crystal case 37. In the groove portion 106, a plurality of grooves are formed that are aligned at the same interval as the opening interval of the terminal openings 84 (see FIG. 7) of the liquid crystal cover 36. Accordingly, even when the liquid crystal case 37 is accommodated in the liquid crystal cover 36 (accommodating portion 58), the terminal opening 84 is not hidden by the liquid crystal case 37, so that the liquid crystal display 16 accommodated in the liquid crystal case 37 is not hidden. The connection terminal 69 can be passed through the terminal opening 84 to the back surface of the liquid crystal cover 36.

Engaging claws 107 projecting rearward from the back surface are formed at both ends in the lateral direction of the back surface of the liquid crystal case 37. The engaging claw 107 is engaged with the engagement receiving portion 104 (see FIG. 7) of the liquid crystal cover 36 when the liquid crystal case 37 is accommodated in the liquid crystal cover 36.
FIG. 9 is a plan view for explaining the assembly structure of the operation / display unit 13 and shows each component in a watermarked manner. 10 is a cross-sectional view for explaining the assembly structure of the operation / display unit 13. FIG. 10 (a) is a cross-sectional view taken along the line AA shown in FIG. 10 (b) is a cross-sectional view taken along the line BB shown in FIG. 9, and FIG. 10 (c) is a cross-sectional view taken along the line CC shown in FIG. In these figures, the side on which the operation / display panel 17 is attached is the front side.

With reference to FIGS. 9 and 10, a control board 33 is placed on the case 19 of the control unit 18.
A liquid crystal cover 36 is attached to the front surface of the control board 33 by, for example, engagement between the engagement claw 100 and the engagement receiving portion 113 of the control board 33 (see FIG. 10B), and further to the screw hole 105. It is fixed by screwing the screw 115 (see FIG. 10C). When the liquid crystal cover 36 is attached, the support member 97 of the liquid crystal cover 36 is interposed between the liquid crystal cover 36 and the control board 33, thereby forming a space 116 between the liquid crystal cover 36 and the control board 33. Has been. Therefore, for example, if the microcomputer 117 is smaller than the microcomputer 38 according to this embodiment (see FIG. 9), the space 116 can be effectively used and disposed on the control board 33.

  A liquid crystal case 37 in which the liquid crystal display 16 is accommodated is accommodated in the liquid crystal cover 36 by engagement of the engagement claw 107 and the engagement receiving portion 104 (see FIG. 10A). A connection terminal 69 (terminal portion) for external connection, which is provided at the lower end of the liquid crystal display 16 and supplies power to the display surface 39, is exposed from the cover portion 76 (terminal opening 84) of the liquid crystal cover 36. For example, it is electrically connected to an electronic circuit formed on the back surface of the control board 33 through a through hole (not shown) formed in the control board 33 (see FIG. 10C).

Further, the operation plate 34 is attached to the front surface of the control board 33 by, for example, engagement between an engagement claw 114 formed on the operation plate 34 and an engagement receiving portion (not shown) of the control board 33. Yes. Further, an operation plate 35 is attached to the front surface of the control board 33 by a method similar to that of the operation plate 34 (engagement between an engagement claw and an engagement receiving portion (not shown)).
On the other hand, as described above, the microcomputer 38 is attached to the back surface of the control board 33 by, for example, solder bonding (see FIG. 10B). Although not shown here, the microcomputer 38 is electrically connected to an electronic circuit connected to the connection terminal 69 of the liquid crystal display 16. Therefore, the microcomputer 38 can control the display of the liquid crystal display 16 through this electronic circuit.

The entire control board 33 is sealed with a urethane resin 111 (a sealing material or a sealing resin) that can be insulated from the outside and can shield heat from the outside.
In particular, in the operation / display unit 13, the urethane resin 111 is connected to the connection terminals 69 and terminals exposed from the cover portion 57 (terminal opening 84) of the terminal cover 36 from the bottom surface of the case 19 in the depth direction within the case 19. The opening 84, the front end portion 123 of the enclosure wall 121, and the front end portion 125 of the enclosure wall 122 are filled. As a result, the connection terminal 69, the front end portion 123 of the enclosure wall 121 and the front end portion 125 of the enclosure wall 122 are covered with the urethane resin 111, and the terminal opening 84 is closed with the urethane resin 111.

  Further, in the operation / display unit 13, an electronic circuit different from the microcomputer area 118 is formed on the bottom wall of the case 19 behind the microcomputer area 118 (first area) to which the microcomputer 38 of the control board 33 is attached. A low step portion 120 is formed that is one step lower than the bottom wall behind the circuit region 119 (second region). As a result, the thickness of the urethane resin 111 on the rear side of the microcomputer area 118 is made larger than the thickness of the urethane resin 111 on the rear side of the circuit area 119 (see FIG. 10B).

The operation / display panel 17 is attached to the control unit 18 by, for example, screwing 112 into the screw hole 109 (see FIGS. 10A and 10C).
In a state where the operation / display panel 17 is attached, the packing 68 is packed in the groove 87 of the liquid crystal cover 36, and the packing 68 is interposed between the liquid crystal cover 36 and the operation / display panel 17. Further, since the packing 68 is crushed in the groove 87 by screwing in the screw 112, the inside of the accommodating portion 58 of the liquid crystal cover 36 is sealed.

The operation / display unit 13 having the assembly structure shown in FIGS. 9 and 10 is incorporated in the electric washing machine 10 as shown in FIGS. 11 and 12.
11 is a cross-sectional view showing the operation / display unit 13 incorporated in the electric washing machine 10. FIG. 11 (a) is a cross-sectional view corresponding to FIG. 10 (b), and FIG. 11 (b) is FIG. It is sectional drawing corresponding to (c). 12 is a plan view of the electric washing machine 10 for explaining the position of the microcomputer 38 in the operation / display unit 13 incorporated in the electric washing machine 10, and is a rear panel and an upper panel constituting the housing 11. FIG. It is a figure of the state from which was removed.

Referring to FIG. 11, the operation / display unit 13 is incorporated in the electric washing machine 10 such that the operation / display panel 17 constitutes a part of the front surface of the housing 11. Thereby, the control unit 18 is arranged inside the electric washing machine 10.
As described above, since the electric washing machine 10 is a device that performs washing using water such as washing and rinsing, the humidity inside the electric washing machine 10 increases during operation and the inside is placed in a high humidity environment. There is.

  Even in such a case, in the electric washing machine 10, the connection terminal 69 exposed from the cover portion 57 (terminal opening 84) of the liquid crystal cover 36 is covered with the urethane resin 111 (FIG. 11B). Reference) Even if the inside of the electric washing machine 10 is in a high humidity environment, the connection terminal 69 is not placed in such an environment. Therefore, even if this electric washing machine 10 is used over time, the connection terminal 69 can be prevented from rusting, and leakage due to the rust of the connection terminal 69 can be prevented. Further, when condensation occurs inside the electric washing machine 10, it is possible to prevent the condensation from touching the connection terminal 69, and thus it is possible to prevent leakage due to condensation inside the electric washing machine 10. .

  Further, since the terminal opening 84 is closed by the urethane resin 111 and the distal end portion 123 of the surrounding wall 121 and the distal end portion 125 of the surrounding wall 122 are covered with the urethane resin 111, the terminal opening 84 and the distal end of the surrounding wall 121 are covered. Steam or moisture enters the liquid crystal cover 36 (liquid crystal case 37) from the portion 123 (opening 99) or the front end portion 125 (engagement receiving portion 104) of the enclosure wall 122, and the liquid crystal display in the liquid crystal cover 36 (liquid crystal case 37). It is possible to prevent the display surface 39 of the vessel 16 from being fogged.

  Such leakage prevention and fogging prevention can be performed by using a part of the urethane resin 111 that seals the control substrate 33. Therefore, it is not necessary to separately prepare a sealing material for covering the connection terminal 69, the distal end portion 123 of the enclosure wall 121 and the distal end portion 125 of the enclosure wall 122, or closing the terminal opening 84, thereby reducing costs. Can do. Further, at the time of manufacture, the control substrate 33 is sealed with the urethane resin 111 in one operation, the connection terminal 69, the coating of the distal end portion 123 of the enclosure wall 121 and the distal end portion 125 of the enclosure wall 122, and the terminal Since the opening 84 can be closed, the manufacturing process can be made more efficient (for example, the manufacturing process can be shortened).

  Further, by forming the enclosure wall 121 and the enclosure wall 122, the entrance of the flow path to the outside through the opening 99 and the engagement receiving portion 104 in the liquid crystal cover 36 is formed in the distal end portion 123 and the distal end portion 125. It becomes the made opening. That is, the positions of the inlets (opening 99 and the engagement receiving portion 104) formed outside the case 19 are the inlets (the tip 123 and the tip 125 formed on the bottom surface side of the case 19 inside the case 19. ) Position. Therefore, in order to prevent the above-described leakage and fogging, it is only necessary to fill the urethane resin 111 from the bottom surface of the case 19 to the front end portion 123 of the enclosure wall 121 and the front end portion 125 of the enclosure wall 122. It is also possible to reduce costs by reducing the amount used.

Further, a packing 68 is interposed between the control unit 18 and the operation / display panel 17 so that the inside of the liquid crystal cover 36 is hermetically sealed so that the passage of vapor and moisture into the liquid crystal cover 36 is reliably blocked. Therefore, fogging of the display surface 39 of the liquid crystal display 16 can be more effectively prevented.
Further, since this electric washing machine 10 is a device that can dry laundry in addition to washing and rinsing, the blower unit 29 is heated by the warm air flowing during the drying operation, and the vicinity of the blower unit 29 is at a high temperature. May be placed in the environment.

Even in such a case, as shown in FIG. 12, the microcomputer 38 is arranged in a region away from the front region of the blower unit 29 in a state where the operation / display unit 13 is incorporated in the electric washing machine 10. Therefore, the microcomputer 38 can be prevented from being heated by the heat of the blower unit 29 and rising in temperature.
Further, the thickness of the urethane resin 111 on the rear side of the microcomputer area 118 to which the microcomputer 38 is attached is made larger than the thickness of the urethane resin 111 on the rear side of the circuit area 119. In other words, in the state where the operation / display unit 13 is attached to the electric washing machine 10, the thickness of the urethane resin 111 that covers the inner side portion of the electric washing machine 10 in the microcomputer area 118 is increased, so that more heat is generated. A blocking effect can be obtained. Further, since the urethane resin 111 is formed thick only in the microcomputer area 118, the temperature rise of the microcomputer 38 can be suppressed with the minimum necessary urethane resin. Furthermore, since the amount of urethane resin can be reduced as a whole at the time of manufacturing, it is possible to improve the efficiency of the manufacturing process (for example, shortening the manufacturing process time, reducing costs, etc.).
