In addition, the sealant covers the terminal portion and closes the terminal opening. And the display part for washing machines of this invention is inserted in a washing machine so that a liquid crystal cover, a terminal part, and a control board may be hidden inside a washing machine, for example.

Since the exposed terminal part in the washing part display part is covered with the sealing material, even if the humidity inside the washing machine increases and the inside of the washing machine is in a high humidity environment, the terminal part is not placed in such an environment. Therefore, even if a washing machine is used, the terminal part can be prevented from rusting over time, and a short circuit caused by the rust of the terminal part can be prevented. In addition, in the case where condensation has occurred inside the washing machine, the condensation can be prevented from coming into contact with the terminal portion, so that a short circuit caused by condensation inside the washing machine can be prevented.

In addition, since the terminal opening is blocked by the sealing material, steam or moisture does not enter the liquid crystal cover from the terminal opening. Therefore, blurring of the display surface of the liquid crystal display housed in the liquid crystal cover can be prevented.

According to the invention of claim 2, the display unit for a washing machine includes a display panel including a display window for making the display surface of the liquid crystal display visible from the outside to the liquid crystal cover so as to seal the inside of the liquid crystal cover through the sealing member.

Therefore, even if the liquid crystal cover is placed in a high-humidity environment during the operation of the washing machine, since the intrusion path of steam or moisture into the liquid crystal cover is reliably blocked, the display surface of the liquid crystal display in the liquid crystal cover can be prevented from blurring.

According to invention of Claim 3, the sealing material which coat | covers the terminal part of a liquid crystal display is formed using the part of sealing resin which seals a control board. Since a part of sealing resin which seals a control board (for example, urethane resin etc.) is used as a material which coat | covers a terminal part, it is not necessary to prepare a sealing material separately, and cost can be held down. In addition, at the time of manufacture, since it can seal in one operation | movement, the efficiency of a manufacturing process (for example, time reduction of a manufacturing process, etc.) can be aimed at.

According to the invention described in claim 4, the liquid crystal cover is fixed to the control substrate by the hook portion. In addition, the liquid crystal cover is provided with a molding hole formed at the time of shaping the hook portion and a molding hole peripheral wall surrounding the molding hole and projecting toward the control substrate. In the state where the liquid crystal cover is fixed to the control substrate, the tip end of the forming hole peripheral wall is covered with a sealing material. Since the molding hole is surrounded by the molding hole circumference wall, the inlet to the intrusion path of the vapor or moisture passing through the molding hole in the liquid crystal cover becomes the tip of the molding hole circumference wall, so that the tip is covered by the sealing material. Invasion of steam or moisture into the liquid crystal cover can be prevented. In addition, since it is only necessary to cover the tip of the wall around the molding hole, the amount of the sealing material used can be reduced to reduce the cost.

According to the invention of claim 5, the control board is housed in the substrate case, and the liquid crystal cover housing the liquid crystal display is mounted on the control board housed in the board case. In the state where the liquid crystal cover is mounted on the control board, the peripheral wall surrounding the opening of the liquid crystal cover protrudes toward the control board. By forming a sealing material in the substrate case, the control substrate is sealed and the tip of the peripheral wall is covered.

And the display part for washing machines of this invention is inserted in a washing machine so that a board | substrate case, a control board, and a liquid crystal cover may be covered inside a washing machine, for example.

In the display portion for the washing machine, since the opening is surrounded by the peripheral wall, the inlet to the intrusion path of the vapor or moisture passing through the opening in the liquid crystal cover is the tip portion of the peripheral wall, so that the tip portion is covered with the sealing material. However, vapor or moisture does not enter the liquid crystal cover from the opening through the peripheral wall. Therefore, blur of the display surface of a liquid crystal display in a liquid crystal cover can be prevented. In addition, since it is only necessary to cover the tip of the peripheral wall, the amount of the sealing material used can be reduced to reduce the cost.

In the manufacturing process, the sealing of the control board and the front end of the peripheral wall can be performed in one operation of introducing the sealing material into the substrate case. Therefore, efficiency of the manufacturing process (e.g., shortening of the manufacturing process time, etc.) can be achieved. We can plan.

According to invention of Claim 6, the washing machine of this invention is equipped with the display part for washing machines in any one of Claims 1-5. Therefore, in this washing machine, it is possible to prevent the short circuit caused by the rust of the terminal portion of the liquid crystal display or the generation of condensation inside the washing machine, and further prevent the blur of the display surface of the liquid crystal display.

According to invention of Claim 7, the display part for washing machines is arrange | positioned at the front surface side of a washing machine, The rear side is provided with the drying air path which circulates the warm air heated by a heater in a processing tank. In addition, the display control apparatus provided in the control board | substrate of the display part for washing machines is arrange | positioned in the area | region which is spaced apart from the area | region of the front side of a drying air path. Therefore, even if the warm air continues to flow through the inside of the drying air passage (the back of the washing machine display unit) during the drying operation of the washing machine, since the display control device is spaced apart from the area in front of the air passage, the display control device is prevented by the heat of the drying air passage. It can suppress heating and temperature rise.

According to the invention described in claim 8, the control substrate has a first region in which a display control device is formed and a second region different from the first region. The control substrate is sealed with a sealing resin for blocking heat from the outside, and the sealing resin is relatively thicker than the rear side of the second region in the rear side of the first region. Since only the thickness of the rear side of the arrangement region (first region) of the display control device which is weak in heat is thickened, the temperature rise of the display control device can be suppressed with the minimum sealing resin required. In addition, at the time of manufacture, since the quantity of sealing resin can be reduced as a whole, efficiency of a manufacturing process (for example, shortening of a manufacturing process, cost reduction, etc.) can be aimed at.

It is installed by a combination. On the front surface of the control board 33, the operation plate 35 is further provided by the same method as the operation plate 34 (coupling of the engaging hook and coupling receiving part (not shown)).

On the other hand, as described above, the microcomputer 38 is provided on the back surface of the control board 33 by solder bonding or the like (see FIG. 10 (b)). 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.

And the control board 33 is sealed by the urethane resin 111 (sealing material, sealing resin) which can insulate from the exterior and can block the heat from the exterior.

In particular, in this operation / display section 13, the urethane resin 111 is covered with a cover portion 57 (terminal opening) of the terminal cover 36 from the bottom surface of the case 19 in the depth direction in the case 19. (84), the connection terminal 69, the terminal opening 84, the tip end 123 of the peripheral wall 121, and the tip 125 of the peripheral wall 122 are filled. Thereby, the connection terminal 69, the tip part 123 of the circumferential wall 121, and the tip part 125 of the circumferential wall 122 are coat | covered with the urethane resin 111, and the terminal opening 84 is urethane resin ( 111).

Moreover, in this operation and display part 13, the microcomputer area | region is at the bottom wall of the case 19 behind the microcomputer area | region 118 (1st area | region) in which the microcomputer 38 of the control board | substrate 33 was installed. Unlike step 118, a lower stepped portion 120 that is further lower than the bottom wall behind the circuit area 119 (second area) in which the electronic circuit is formed is formed. Thereby, the thickness of the urethane resin 111 in the rear side of the microcomputer region 118 becomes thicker than the thickness of the urethane resin 111 in the rear side of the circuit region 119 (FIG. 10). (b)].

The control unit 18 is provided with an operation / display panel 17 by, for example, inserting 112 into the screw hole 109 (Fig. 10 (a) and Fig. 10 (c)). ) Reference].

In the state where the operation and display panel 17 is installed, the packing 68 is filled in the groove 87 of the liquid crystal cover 36, and this packing 68 is connected to the liquid crystal cover 36 and the operation and display panel 17. It is interposed in between. In addition, since the packing 68 is pressed and crushed in the groove 87 by the insertion of the screw 112, the inside of the accommodating portion 58 of the liquid crystal cover 36 is in a sealed state.

And the operation / display part 13 which has an assembly structure shown in FIG. 9 and FIG. 10 is inserted in the electric washing machine 10 as shown to FIG. 11 and FIG.

FIG. 11 is a sectional view showing the operation / display section 13 inserted into the electric washing machine 10, FIG. 11A is a sectional view corresponding to FIG. 10B, and FIG. 11B is a FIG. It is sectional drawing corresponding to (c) of this. 12 is a plan view of the electric washing machine 10 for explaining the position of the microcomputer 38 in the operation / display section 13 inserted into the electric washing machine 10, and the back of which constitutes the housing 11. The panel and the top panel are removed.

Referring to Fig. 11, the operation / display section 13 is inserted into the electric washing machine 10 so that the operation / display panel 17 constitutes a part of the front face of the housing 11. As a result, the control unit 18 is disposed inside the electric washing machine 10.

As described above, since the electric washing machine 10 is a device that washes using water such as washing and rinsing, the humidity inside the electric washing machine 10 increases during operation, and the inside may be placed in a high humidity environment.

Even in such a case, in this 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 [ 11 (b)], 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, the connection terminal 69 can be prevented from rusting over time, and the short circuit resulting from the rust of the connection terminal 69 can be prevented. In addition, when the dew condensation generate | occur | produces inside the electric washing machine 10, since the dew condensation can be prevented from contacting the connection terminal 69, the electric leakage resulting from the dew condensation inside the electric washing machine 10 can also be prevented. .

In addition, since the terminal opening 84 is blocked by the urethane resin 111, and the front end portion 123 of the peripheral wall 121 and the front end portion 125 of the peripheral wall 122 are covered with the urethane resin 111, the terminal Vapor or moisture is released from the opening 84, the tip 123 (opening 99) of the peripheral wall 121, or the tip 125 (combination receiving part 104) of the peripheral wall 122. It is possible to prevent the display surface 39 of the liquid crystal display 16 in the liquid crystal cover 36 (liquid crystal case 37) from entering the [liquid crystal case 37].

In addition, such a short circuit prevention and a blur prevention can be performed by using a part of urethane resin 111 which seals the control board 33. FIG. Therefore, it is not necessary to cover the connection terminal 69, the tip part 123 of the circumference wall 121, and the tip part 125 of the circumference wall 122, or to prepare the sealing material for blocking the terminal opening 84. The cost can be kept down. At the time of manufacture, the urethane resin 111 is used to seal the control board 33, the connecting terminal 69, the tip 123 of the peripheral wall 121, and the tip of the peripheral wall 122 in one operation. Since the covering of the 125 and the terminal opening 84 can be closed, the manufacturing process can be made more efficient (e.g., a shorter time for the manufacturing process, etc.).

In addition, since the peripheral wall 121 and the peripheral wall 122 are formed, the entrance of the flow path to the outside through the opening 99 and the coupling receiving part 104 in the liquid crystal cover 36 is formed. Openings are formed in the tip portion 123 and the tip portion 125. That is, the position of the entrance (opening 99 and the engaging receiving part 104) formed in the outer side of the case 19 is the entrance (tip part 123) formed in the bottom surface side of the case 19 which is inner side of the case 19. And tip portion 125]. Therefore, in performing the electric leakage prevention and the blur prevention mentioned above, the urethane resin 111 is made from the bottom surface of the case 19, the front end 123 of the circumferential wall 121, and the front end 125 of the circumferential wall 122. Since it is good to just fill up to, the cost of the urethane resin 111 can be reduced.

In addition, a packing 68 is interposed between the control unit 18 and the operation and display panel 17, so that the inside of the liquid crystal cover 36 is sealed, so that the inflow path of steam or moisture into the liquid crystal cover 36 is prevented. Since it is blocked reliably, the blur of the display surface 39 of the liquid crystal display 16 can be prevented more effectively.

In addition, since the electric washing machine 10 is a device capable of drying laundry as well as washing and rinsing, the electric washing machine 10 is heated by the warm air flowing through the blower unit 29 during the drying operation so that the surroundings of the blower unit 29 are exposed to a high temperature environment. There is a case to be set.

Even in such a case, as shown in Fig. 12, the microcomputer 38 is spaced apart from the area in front of the blower unit 29 in a state where the operation / display section 13 is inserted into the electric washer 10. Since it is arrange | positioned at the area | region, it can suppress that the microcomputer 38 is heated by the heat of the blower unit 29, and temperature rises.

In addition, the thickness of the urethane resin 111 in the rear side of the microcomputer region 118 where the microcomputer 38 is installed is thicker than the thickness of the urethane resin 111 in the rear side of the circuit region 119. It is. That is, since the operation / display part 13 is provided in the electric washing machine 10, since the thickness of the urethane resin 111 which covers the inner side part of the electric washing machine 10 of the microcomputer area 118 becomes thick, The heat blocking effect can be obtained further. Moreover, since the urethane resin 111 is thickly formed only in the microcomputer region 118, the temperature rise of the microcomputer 38 can be suppressed with the minimum urethane resin required. In addition, at the time of manufacture, since the quantity of urethane resin can be reduced as a whole, efficiency of a manufacturing process (for example, shortening of a manufacturing process, cost reduction, etc.) can be aimed at.
