Description

The present invention relates to an electrical device with a display function.

Some conventional electrical appliances with display functions (e.g., rice cookers) have a display unit mounted on the control board (see, for example, JP 2016-168197 A).

JP 2016-168197 A

However, in electrical devices such as those described above, condensation may occur on the display depending on the installation environment. The objective of the present invention is to prevent condensation on the display of electrical devices with a display function.

The electrical device with a display function according to the present invention comprises:
A display device;
A cover portion disposed on a display surface side of the display device;
a control board connected to the display device via wiring and controlling the display device ;
a sealing member that, together with the cover portion, forms a space that seals the display device ;
The control board is located outside the space .

According to the above configuration, the display device can be sealed using a sealing member. Therefore, by sufficiently dehumidifying the sealed space during manufacturing, it is possible to prevent condensation on the display unit thereafter. Also, here, the sealing member can be made smaller and the sealed space can be made smaller than when both the display device and the control board are sealed. Therefore, compared to when both the display device and the control board are sealed, the sealed space can be dehumidified relatively quickly and the amount of desiccant put into the sealed space can be reduced.

In the present invention,
the sealing member includes a mounting member on which the display device is mounted, and a first seal member sandwiched between the mounting member and the cover portion,
The mounting member has a through hole formed therein,
the wiring member passes through the through hole of the mounting member and reaches the control board,
It is preferable that the device further includes a blocking member that blocks the through-hole when the wiring material is passed through the through-hole.

The above configuration makes it easier to pull out the wiring material from the mounting member during assembly, which is expected to improve work efficiency.

In the present invention,
the placement member is a container having an opening, and the display device is placed on the placement member such that a display surface of the display device faces the opening;
The first seal member is preferably sandwiched between an edge portion that defines the opening and the cover portion.

With the above configuration, the display device can be viewed only through the cover, making it easier for the viewer to view the display device.

In the present invention,
A second seal member is further provided to sandwich the wiring material.
It is preferable that the blocking member closes the through hole together with the second seal member.

The above configuration effectively prevents moisture from entering the enclosed space.

These components will be described in detail below.

1 to 3, the housing 111 is mainly composed of a container 111a, a shoulder member 111c, and a protective frame (not shown), and houses a heat insulating material (not shown), a ferrite core (not shown), an induction heating coil 112, a blower fan unit 116, a power supply circuit board 117, an automatic retractable power cord unit 118, etc. Each of the components of the housing 111 will be described in detail below.

As shown in Figs. 1 to 3, the housing 111a is mainly formed of a side wall portion 111x and a bottom wall portion 111y. The side wall portion 111x is a cylindrical enclosure wall portion having a substantially rounded rectangular shape in a plan view. The bottom wall portion 111y is a substantially rounded rectangular corner dish-shaped portion in a bottom view, and is formed on the lower side of the side wall portion 111x as shown in Fig. 3. As shown in Fig. 3, an intake port SO for drawing air from outside the housing 111 into the inside is formed on the rear side of the bottom wall portion 111y, and an exhaust port (not shown) for discharging air from inside the housing 111 to the outside is formed on the front side of the bottom wall portion 111y. As shown in Fig. 3, a blower fan unit 116 is arranged above the intake port SO. When the blower fan unit 116 is driven, external air is drawn into the housing 111 through the intake port SO, and the resulting air flow expels the heated air from the inside to the outside of the system through the exhaust port. In addition, a receiving tray portion RD is formed in the bottom wall portion 111y as shown in FIG. 3. As shown in FIG. 3, the receiving tray portion RD is bulged downward (recessed/dented) near the center in the depth and width directions. As shown in FIG. 3, the receiving tray portion RD is formed with a plurality of drainage ports EP.

The shoulder member 111c is a frame body having a generally rounded rectangular shape in a plan view, and is fitted to the upper side of the side wall portion 111x of the container 111a as shown in Figs. 1 and 3, covering the edge of the upper opening of the container 111a. A generally circular opening is formed in the shoulder member 111c for inserting the inner pot 130. A protective frame is attached to the underside of the shoulder member 111c. The protective frame is attached to the shoulder member 111c by a protective frame flange portion (described later).

The display device DI is used to display various information such as cooking progress information and the cooking menu selected by the user, and is composed of a liquid crystal display, an organic EL display, etc. The display device DI is placed on the display device mounting member DP of the display device sealing member DS with the display surface facing upwards (i.e., the display surface faces the transparent window TW) (see Figures 3 to 6). The display device DI is connected to the control circuit board CT via a flexible printed circuit board FL and a connection connector CN, as shown in Figures 4 and 5.

(6) Display Device Sealing Member The display device sealing member DS is a member for sealing the display device DI together with the upper exterior body 142a, and is composed of a display device mounting member DP and a packing PK as shown in Figures 4 to 6. These components will be described in detail below.

The display device mounting member DP is a member for mounting the display device DI, and is mainly formed of a bottom wall portion DP1, an inner wall portion DP2, an outer wall portion DP3, a positioning wall portion DP4, a positioning rib DP5, a first mounting portion DP6, and a second mounting portion DP7, as shown in FIG. 7. The bottom wall portion DP1 is a plate-like body having a substantially rectangular shape in a plan view, as shown in FIG. 6 and FIG. 7. In addition, a double-sided tape (not shown) is attached to the area surrounded by the positioning wall portion DP4 and the positioning rib DP5 on the upper surface of the bottom wall portion DP1. The display device DI is placed in this area on the upper surface of the bottom wall portion DP1, and is attached to the bottom wall portion DP1 by this double-sided tape (see FIG. 5). In addition, as shown in FIG. 5 to FIG. 7, a through hole DPa extending in the left-right direction is formed in the right rear part of the bottom wall portion DP1 in the area surrounded by the inner wall portion DP2. As shown in FIG. 5, the flexible printed circuit board FL passes through this through hole DPa. In addition, screw receiving portions (not shown) are formed on the left and right sides of the through hole DPa on the lower surface of the bottom wall portion DP1, and screws are screwed into these screw receiving portions and the screw holes BLb of the blocking member BL to fasten the display device mounting member DP and the blocking member BL. As shown in FIG. 5 to FIG. 7, the inner wall portion DP2 is a substantially rectangular cylindrical surrounding wall having a square shape in a plan view, and extends upward from a portion of the bottom wall portion DP1 that is inside the outer end (i.e., the inner wall portion DP2 is formed inside the outer wall portion DP3). As shown in FIG. 5 to FIG. 7, the outer wall portion DP3 is a substantially rectangular cylindrical surrounding wall having a square shape in a plan view, and extends upward and downward from the outer end of the bottom wall portion DP1 (i.e., the outer wall portion DP3 is formed outside the inner wall portion DP2). As shown in Figs. 5 and 7, a ring-shaped groove DPb is formed by the bottom wall DP1, the inner wall DP2, and the outer wall DP3. As shown in Figs. 4 and 5, a packing PK is fitted into this groove DPb. As shown in Figs. 6 and 7, the positioning wall DP4 extends upward from the front left and front right parts of the bottom wall DP1 so as to be located inside the inner wall DP2. As shown in Figs. 6 and 7, the positioning rib DP5 is a rib that extends inward from the inner surface of the rear part, the inner surface of the left part, and the inner surface of the right part of the inner wall DP2. When the display device DI is placed in the range surrounded by the positioning wall DP4 and the positioning rib DP5 on the upper surface of the bottom wall DP1, the position of the display device DI is fixed by the double-sided tape, the positioning wall DP4, and the positioning rib DP5. As shown in FIG. 6 and FIG. 7, the first attachment portion DP6 extends outward from the four corners of the outer wall portion DP3 and has a generally cylindrical shape. The first attachment portion DP6 is used when attaching the display device mounting member DP to the upper exterior body 142a. As shown in FIG. 6 and FIG. 7, the second attachment portion DP7 extends outward from the left side surface of the outer wall portion DP3 and the right side surface of the outer wall portion DP3. The frame body 143a of the operation board 143A is placed on the upper surface of this second attachment portion DP7. In addition, a screw hole (not shown) is formed at the outer lower end of the second attachment portion DP7, and a screw is screwed into this screw hole and the screw hole CT1 of the control circuit board CT to fasten the display device mounting member DP and the control circuit board CT.

As shown in Figures 4 to 6, the packing PK is an annular member that is fitted into the groove portion DPb of the display device mounting member DP and serves to seal the gap between the upper exterior body 142a and the display device mounting member DP by being in close contact with the upper exterior body 142a and the display device mounting member DP.

(7) Flexible Printed Circuit Board The flexible printed circuit board FL is an electrical wiring member for connecting the display device DI to the control circuit board CT via the connector CN. As shown in Fig. 4 and Fig. 5, one end of the flexible printed circuit board FL is connected to the display device DI, and the other end of the flexible printed circuit board FL is connected to the connector CN. As described above, the flexible printed circuit board FL passes through the through hole DPa of the display device mounting member DP. Furthermore, as shown in Fig. 5 and Fig. 8, the flexible printed circuit board FL passes through the opening SLa of the upper seal member SL1 of the through hole seal member SL, and a part of the flexible printed circuit board FL is sandwiched between the upper seal member SL1 and the lower seal member SL2.

(8) Closing member The closing member BL is a member for closing the through hole DPa of the display device mounting member DP together with the through hole seal member SL, and is formed of a main body portion BL1 and a flange portion BL2 as shown in Fig. 5, Fig. 6 and Fig. 8. The main body portion BL1 has a substantially rectangular parallelepiped shape as shown in Fig. 5, Fig. 6 and Fig. 8. Also, as shown in Fig. 5, a recessed portion BLa is formed from the center of the lower surface of the main body portion BL1 to the vicinity of the upper surface. As shown in Fig. 5 and Fig. 8, a lower seal member SL2 of the through hole seal member SL is disposed on the upper surface of the main body portion BL1. As shown in Fig. 5, Fig. 6 and Fig. 8, the flange portion BL2 extends outward from the center of the height direction of the main body portion BL1 and has a substantially L-shape. As shown in Figs. 6 and 8, screw holes BLb for fastening the blocking member BL and the display device mounting member DP are formed on the left and right sides of the flange portion BL2.

(9) Through-hole seal member The through-hole seal member SL is a member for closing the through-hole DPa of the display device mounting member DP, and has contractibility. As shown in FIG. 5, FIG. 6, and FIG. 8, the through-hole seal member SL1 is a rectangular plate-like body with an opening SLa formed in the center (i.e., the upper seal member SL1 has a square shape). As described above, the flexible printed circuit board FL passes through this opening SLa. In addition, in a plan view, the front-rear and left-right dimensions of the opening SLa are larger than the front-rear and left-right dimensions of the through-hole DPa of the display device mounting member DP. In addition, the upper seal member SL1 is disposed below the bottom wall portion DP1 of the display device mounting member DP so that the entire area of the through-hole DPa of the display device mounting member DP overlaps with the area of the opening SLa in a plan view (see FIG. 5 and FIG. 6). The lower seal member SL2 is a rectangular plate-like body as shown in Figures 5, 6 and 8. As shown in Figures 5, 6 and 8, the front-rear and left-right dimensions of the lower seal member SL2 are approximately the same as those of the upper seal member SL1, but the thickness of the lower seal member SL2 is greater than that of the upper seal member SL1. As shown in Figures 5, 6 and 8, the lower seal member SL2 is disposed between the upper seal member SL1 and the blocking member BL, and sandwiches a part of the flexible printed circuit board FL together with the upper seal member SL1.

By configuring the display device mounting member DP, blocking member BL and through-hole seal member SL in this manner, when a screw is screwed into the screw receiving portion (not shown) of the bottom wall portion DP1 of the display device mounting member DP and into the screw hole BLb of the blocking member BL to fasten the display device mounting member DP and the blocking member BL, the through-hole seal member SL is sandwiched between the display device mounting member DP and the blocking member BL. And since the through-hole seal member SL has contractibility, it contracts in the vertical direction. As a result, the through-hole DPa of the display device mounting member DP is sealed.

(10) Connector As shown in FIGS. 4 to 6, the connector CN is a member for connecting the display device DI to the control circuit board CT via the flexible printed circuit board FL, and is fitted into the control circuit board CT.

(11) Control Circuit Board The control circuit board CT is a board constituting a control circuit, and is disposed below the display device sealing member DS as shown in Figures 3 to 6. The control circuit board CT has electronic components such as a microcomputer mounted thereon, and is communicatively connected to the operation buttons 143, the display device DI, the solenoid of the power failure pressure release valve, and the like, and is communicatively connected to the induction heating coil 112 of the main body 110, the center sensor 114, the warming heater 115, the blower fan unit 116, and the like via the power supply circuit board 117.

(12) Pressure Regulating Device The pressure regulating device 144 regulates the pressure inside the inner pot 130 to 1.03 to 1.3 atmospheres when the lid 140 is closed and pressure cooking is in progress. The pressure regulating device 144 is disposed above the inner lid 146 as shown in FIG. 3 .

(13) Power failure pressure relief valve The power failure pressure relief valve is a safety valve operated by a solenoid, and is disposed adjacent to the pressure regulator 144 on the upper side of the inner lid 146. When the power to the solenoid coil is cut off due to, for example, a power failure or a plug being pulled out, the power failure pressure relief valve opens to release the pressure inside the inner pot 130.

(14) Inner Lid As shown in Fig. 3, the inner lid 146 is a member for covering and sealing the upper part of the inner pot 130, and is detachably attached to the underside of the lid base plate 141. As described above, the pressure regulator 144 and the power failure pressure release valve are disposed on the upper side of the inner lid 146.

(15) Steam Processing Unit The steam processing unit 147 is for releasing steam rising from the inner pot 130 during cooking to the outside and for recovering sticky components, and is disposed at the rear of the upper exterior body 142a as described above. As shown in Figures 1 to 3, a steam port BO extending in the left-right direction is formed in the center of the upper wall of this steam processing unit 147, and steam is released to the outside through this steam port BO.

(16) Opening/Closing Mechanism The opening/closing mechanism OC is a mechanism that controls the opening and closing of the lid body 140, and as shown in Fig. 3, is disposed in the front part of the lid body 140, and is mainly composed of an opening/closing button BT and a lever member LP. These components will be described in detail below.

The open/close button BT is a rounded rectangular button for opening and closing the cover 140, and is located above the lever member LP. The open/close button BT is biased upward by a coil spring.

The lever member LP is a metal plate member formed from an abutment plate portion (not shown), a pair of left and right extension plate portions (not shown) extending downward from the front side of the abutment plate portion, claw portions (not shown) extending rearward from the lower portion of each extension plate portion, and a pivot shaft LP1, and is supported by the pivot shaft LP1 on the exterior body 142, and is biased upward by a coil spring (not shown) at the rear end of the abutment plate portion. When the user presses down on the open/close button BT, the lower end portion of the open/close button BT abuts against a portion of the abutment plate portion of the lever member LP that is rearward of the pivot shaft LP1.

When the user wishes to close the lid 140, the user does not need to operate the open/close button BT, but simply tilts the lid 140 toward the main body 110. At this time, the claw portion of the lever member LP moves downward while contacting the inclined surface (not shown) formed in the shoulder member 111c. During this time, the lever member LP rotates forward against the biasing force of the coil spring. Then, when the claw portion reaches the claw receiving hole (not shown) formed in the shoulder member 111c, the claw portion fits into the claw receiving hole due to the biasing force of the coil spring. In this way, the lid 140 is in the closed state. On the other hand, when the lid 140 is to be opened, the user presses down the open/close button BT. Then, the lower end portion of the open/close button BT comes into contact with the abutment portion of the lever member LP, and the lever member LP rotates forward against the biasing force of the coil spring. At this time, the claw portion that was fitted into the claw receiving hole is pulled out of the claw receiving hole. The lid 140 is then lifted upward by the biasing force of the hinge part 150, and the lid 140 enters an open state.

4. Hinge Part As described above, the hinge part 150 attaches the cover 140 to the main body 110 so that the cover 140 is rotatable relative to the main body 110. The hinge part 150 biases the cover 140 in the opening direction.
